Question about Office Equipment & Supplies

The formula for a hypotenuse is a ^2 + b^2 = c^2, where a and b are the sides and c is the hypotenuse.

For example, if the sides are 3cm and 4cm, calculate the hypotenuse.

3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^2

To get c by itself, we have to take the square root of each side.

25^ (1/2) = (c^2)^(1/2)

5 = c

Good luck.

Hi David:

You've got me confused.

A triangle has 3 sides. You have provided 4 lengths and no picture.

The hypotenuse is joins the 2 sides that are the "legs" of the right angle.

The length of the hypotenuse is the square root of the sum of the squares of the sides.

Just apply the "rule" to the appropriate dimensions.

Cheers

The formula to calculate the hypotenuse of a right angled triangle is a^2 + b^2 = c^2 or in words, a squared plus b squared is equal to c squared. The most common mistake is that students make the hypotenuse a squared or b squared. The hypotenuse has to be c squared. Thus, when figuring out the sides of a right-angled triangle, always make sure the hypotenuse is the longest side.

For example, a triangle with sides of length 3 and 4, calculate the hypotenuse. Let a be 3 and b be 4. 3^2 + 4^2 = c^2 or 9+16 = c^2, or 25 = c^2. Now take the square root of both sides and we get c = 5.

"Hypotenuse" implies a right angle triangle is wanted here. With Pythagoras' Theorem it is always good to look first for a 3-4-5 pattern, the simplest ratio, although a right angle triangle easily can be other ratios too.

24 x 32 is (3 x 8) x (4 x 8) so it is a 3-4-5 triangle after all, and the hypotenuse is then 5 x 8 = 40

Or, you could calculate SQRT (24^2 + 32^2) = 40

24 x 32 is (3 x 8) x (4 x 8) so it is a 3-4-5 triangle after all, and the hypotenuse is then 5 x 8 = 40

SOHCAHTOA.

Sine is the Opposite divided by the Hypotenuse.

Let's use a triangle with both sides equal to 1 and the hypotenuse will be a^2 + b^2 = c^2, or 1^2 + 1^2 = c^2, or c^2 = 2, so c = square root (2).

So in this triangle, the sin 45 degrees is 1/square root 2 or 0.7071.

Sin square 45 is really sin 45 squared. So we get our answer 0.7071 and square it, and we get 0.5.

Good luck.

cos A = adjacent/hypotenuse
= 19/24

A = Inverse cos (19/24) = 37.66

P.S. Also, make sure your calculators settings is in degrees (not radians or grads)

in a 45-45-90 triangle, the lengths of the sides are in a ration, 1:1:√2, so if you have one side of the triangle, such as a leg, with the value in the ratio of 1, simply multiply that given number by √2 to get the hypotenuse, if you're instead given the hypotenuse, simply divide by √2 to get the answer for one of the legs. The legs of a 45-45-90 triangle are equal.

I hope this helps!

In right triangle we are making 90 degree angle triangle, we can have problem for finding hypotenuse or finding sin or cos values of the side of the triangle.
For ex,Find out the hypotenuse,sin and cos value of the right triangle with base 4 cm and perpendicular 3 cm
Solution:Hypotenuse = SQRT(4^2 + 3^2)
=SQRT(4*4 + 3*3)
=SQRT(16+9)=SQRT(25)=5 cm
For right triangle,
sin(x)=3/5=0.6
cos(x)=4/5 =0.8

The 3 trig functions most commonly

used in triangle calculations are

sine = Opposite/Hypotenuse Co secant = Hypotenuse/Opposite

Cosine = Adjacent/Hypotenuse The reciprocals are Secant = Hypotenuse/Adjacent

Tangent = Opposite/ Adjacent Cotangent = Adjacent/Opposite

Hope this helps Loringh

A squared + B squared = C squared

15 squared + 15 squared = C Squared

225 + 225 = c squared

450 = c squared

the square root of 450 is 21.21320433

15 squared + 15 squared = C Squared

225 + 225 = c squared

450 = c squared

the square root of 450 is 21.21320433

Hi John , I want to help you with your question, but I need more information from you. Can you please add details in the comment box? The information of "this triangle" is missing in order to find the hypotenuse.
