A right triangle has an angle of 0.37 radians. If the adjacent is 9 meters, find the length of the hypotenuse

Question

help me please

Answer 1

let x = length of hypotenuse

 

Then, cos(0.37) = 9/x

 

So, xcos(0.37) = 9

 

                     x = 9/cos(0.37) ≈ 9.65

Answer 2

We will use cosine, since cosθ = adjacent side over hypotenuse.

 

cos(0.37π) = 9 / x

 

 

x = 9 / (cos(0.37π))

 

x = 22.66

 

The length is 22.66 meters.
