Question

Please helpppppp:)))))

Answer 1

Answer:

x = 31.8

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos x = adj / hyp

cos x = 17/20

Taking the inverse cos of each side

cos^-1 (cos x)  =  cos^-1( 17/20)

x =31.78833062

To the nearest tenth

x = 31.8

Answer 2

Since this is a right triangle, we can use trigonometry to solve. We'll use one of the three main trigonometric functions: sine, cosine, or tangent.

Remember: SOH-CAH-TOA

Looking at our unknown angle, we know the adjacent side and the hypotenuse. Therefore, we should use cosine.

cos(x) = 17/20

To solve, use the inverse cosine function (cos^-1) on your calculator.

x = 31.8 degrees

Hope this helps!
