Use general Pitagora's theorem ( if you can not just make the measurements) ...I mean get the long one on the ground ..and after that measure with a protractor the angle ..and draw the second one ..when you draw a line from the ends of the 2 of them you will have the 3rd.
or ..this is the Pitagora's theorem in general cases..
BC2=AB2+AC2-2*AB*AC*cosA
meaning

BC2 =48.6sqre+66sqre -2 x 48.6 x 66 x R(3)/2 whwre R(3) is the square root from 3 and R(3)/2 is the cos 30"
and will be with approximation
BC=24.44

I am unable to cut 5" baseboard at 45 degree angle


from your last post this information was missing
when cutting at an angle the cut depth is always reduced and the 5" board is too thick
to do what you want the saw will have to be 10" or bigger because when cutting at an angle you are cutting a hypotenuse which is the longest dimension of a triangle
so if the saw cuts to a depth of 5" at right angles the angle cut will be longer because of the triangle effect

Simple pendulum


When giving physical quantities you cannot omit the units. (an angle of 10 what). You cannot solve the problem fully because you are missing the length of the pendulum.
You cannot use any kinematic relations because the expression of the period depends on the assumption that angles of rotation remain small.
You will have to use the energy conservation principle. Assuming that the mass was released with 0 initial kinetic energy, the kinetic energy at the lower point (angle 10 degrees) is equal to the change in potential energy between the release point and the point where the mass is.
(1/2)mv^2=delta Ep= Ep(30 deg)-Ep(10 deg)
Once you calculate the potential energy (see screen capture) difference you will see that it is proportional to m*g, so the mass will cancel out.
fa4a24ac-c4c2-48d5-9f73-9560389da196.pngYour turn: Calculate the potential energy difference between the positions at 30 deg and 10 deg, equate the result with the kinetic energy and solve for v^2, and hence for v the tangential velocity.

Sin 43 degrees 30'


Press SIN 4 3 2ND [ANGLE] 1 3 0 2ND [ANGLE] 2 ENTER

2ND [ANGLE] 1 gives you the degrees symbol, 2ND [ANGLE] 2 gives you the minutes symbol. If you need seconds, use ALPHA ["] (on the + key).

Note that this usually won't give you an EXACT value, but only a ten-digit approximation.

A scalene triangle has side measuremnts a=43, b=55, c=30 . Angle a plus Angle b must equal 43. Angle b plus Angle c must equal 55. Angle c plus Angle a must equal 30.


Answer: angle a=9 degree angle b=34 degree angle c=21 degree Explanation: we have, a+b=43............(1) c+b=55..............(2) c+a=30..............(3) from (3) we get, c=30-a...........(4) substituting value of c from (4) in (2) we get, 30-a+b=55.........(5) a+b=43..........(1) (5)-(1) give 30-2a=12 30-12=2a a=18/2=9 degree giving value of 'a' in (1) 9+b=43 b=34 degree similarly giving value of 'a' in (3) c+9=30 c=21 degree

Sine graph is straight


If the angle unit is set to degrees and you use the standard window dimensions (Xmin=-10, Xmax=10) then all you will see is a straight line: Between 0 and 10 degrees, the sine is approximately equal to 0 and the cosine is about 1.

To see the features of the trigonometric functions you must do one of the following
  1. Set angle to degree but set window dimensions to span the domain -180 to 180 or larger.
  2. Set windows dimensions to the standard -10, 10 range but set angle degree to radians

How to switch from the decimal degree to degrees, minutes, seconds


Keys 1. I displays the following menu that lets you change the angle mode setting to DEG, RAD, and GRD without affecting the value in the display. DEG Sets degree mode. RAD Sets radian mode. GRD Sets gradient mode. The default setting is DEG. 2. = displays a menu that lets you specify the unit of an angle. º Specifies degrees. å Specifies minutes. æ Specifies seconds. r Specifies radians. g Specifies gradients. DMS Lets you convert an angle from decimal degrees to DMS notation. Notes · The examples on the transparency masters assume all default settings. · Angles with a trig function ignore the angle mode setting and display results in the original unit. Otherwise, angles (without a trig function) are converted and displayed according to the angle mode setting. · You enter decimal-degree angles the same as you would any other number. · For decimal/DMS conversions, the calculator interprets all values as degrees, regardless of the angle-unit setting. · DMS angles are entered as º (degrees), ´ (minutes), and ´´ (seconds You watched 2 videos that were 2:05 (2 hours and 5 minutes) and 1:46 (1 hour and 46 minutes) in length.

How can i do because my calculator cannot graph trig trigonometric functions


When dealing with trigonometric functions and their inverses one has to make sure the angle unit is chosen accordingly.
I am including a few screen capture to help you do the graph.
First, in Home screen Run the NewProb command to reset the calculator and ready it as a clean slate.
f967d69.jpg

Set the correct angle unit. By default, after the NewProb command the angle unit is reset to Radian. If you want something else change it. See picture. Select 1:radian or 2:Degree.
I will use Radian first.
ca5d4d2.jpg

Press the key sequence that opens the Y= editor. Enter Y1=sin(X)
c4f7cdf.jpg

Remember after a newProb command unit is Radian, Window is standard.
Here is what you get.
c0e63f3.jpg

Here are the window dimension that gave this picture
f2629f9.jpg

Now I am going to change the angle unit to degree and redraw a better framed graph. (I could have done it with the radian unit too.)
As you can see I played with the window dimensions (Xmin=-3*180=-540 and Xmax=3*180=540. The Xscale factor was set to 90 and the range of y-values was reduced to -1.2 to 1.2)

Here is what you get

Before hitting the Graph sequence make sure that the function to be drawn has a check mark to its left (see the 3rd screen capture from the top).

How do I calculate the ArcCos of say -.25? When I use the TI-84 Plus Silver Edition I first press 2nd the Cos to obtain Cos-1. I then put in -.25 and close parenthesis ) and then enter. The value I get is...


Hello,
There is nothing wrong. Your angle unit is set to radians and the calculator gave you the correct angle the cosine of which is -0.25: the answer is in the same unit as the one your calculator is configured for.
Press [MODE]. Use arrow to scroll to 3rd line, highlight Degree and press [ENTER]. Press [2nd][QUIT] to return to main calculator screen.
As long as the angle unit is set to degree, the angles calculated by the inverse trigonometric function will be in degrees.

Hope it helps.
