Angle of depression

I need an illustration and solution..plss..



Lauren was standing on the pier at the beach approach trying to find her sister. She spotted her at the water’s edge at an angle of depression of 28°. If the pier is 5 yards above the sand, how far down the beach is Lauren’s sister?

angle of depression - 9cd8f44.jpg ð XAC = ð ACB (Angle of elevation= Angle of depression)
AB = 5 Yards
BC = ?
Now Tan C= AB/BC
BC = AB/ Tan C
BC = 5 / Tan 28 Yards
BC = 5/.531709 Yards
BC = 9.403632 Yards

A right angle triangle with length of AB 10cm and AC 20cm, how do I find the angle of BC


Assuming that the angle at A is the right angle, Pythagoras' theorem says that the length of the hypotenuse (the side opposite the right angle) is the square root of the sum of the squares of the other two sides. In your case, AB and AC are 'the other two sides' and BC is the hypotenuse, so:

/ 2 2 /
length BC = V 10 + 20 = V 100 + 400


= V 500 = 22.36 cm

(To find the angle at C, you need trigonometry and is arc-tan(10/20)

and the angle at B is arc-tan(20/10) - 26.5 deg and 63.5 deg)

Why is tan90 not defined?


The tangent of an angle (in a right triangle) is defined to be the length of the side opposite the angle, divided by the length of the side adjacent to the angle (that is not the hypoteneuse). As the angle approaches 90 degrees, the length of the opposite side gets very large and the length of the adjacent side nears 0. At 90 degrees, the length of the adjacent side is 0, and division by 0 is not defined, so the tangent of 90 degrees is not defined.

(5x-15)+(3x+5)=180 angle a = (5x-15) degrees (obtuse) angle b = (3x+5) degrees (acute) both angles are supplementary to each other equaling 180 solving for x


Solve for x
5x+3x+(-15) + 5 becomes 8x-10=180
move 10 from left to right and you get8x190
8x = 190
x = 23.75
so the first angle is (5*23.75)-15 = 103.75
and the second angle is (3*23.75) +5 = 76.25

check by adding 76.25+103.75 = 180

Make sense? I love math, let me know it you need more help

An airplane is flying at a height of 2 miles above the ground. The distance along the ground from the airplane to the airport is 5 miles. What is the angle of depression from the airplane to the airport?


a2+b2=c2
a being your height, b is your distance from the airport and c is the distance from the airport to the plane........ so the answer is 5.385164807134504 miles

I need an urgent help..pleassssssssseeeee....


cafdef1.jpg Given AC = 2675 feet
ð XAC= 14 degree
Therefore ð ACB = 14
Now Sin C= AB/AC
AB = AC . Sin C
AB = 2675 * Sin 14 feet
AB = 2675 * 0.241922 feet
AB = 647.1411 feet

Hi Jehho soria

Draw a right triangle with the vertical portion of the triangle representing the 37 meters of the light house The base of the triangle is the distance we are trying to find. If the angle of depression is 15 degrees, the other angle is 75 degrees. This is the angle from the boat to the top of the lighthouse.

so The Tangent of 75 degrees is equal to the side opposite the angle (the height of the lighthouse) divided by the side adjacent (the distance we are trying to find.

solving for the distance we get distance = 37 divided by the tangent of 37 degrees

Looking up the tangent of 15 degrees on google give .2679

dividing 137 by .2679=138,1 meters

Hope this helps Loringh PS Please leave a rating for me.
