In the triangle below, x=? . round to the nearest tenth.

58 deg

Step-by-step explanation:

Look at x and then look at the sides that are given... 9 is adjacent and 17 is the hypotenuse so use cosine.

cos(x)=9/17

To solve for x just use arccos( ) or cos^(-1)

Type cos^(-1)(9/17) into calc to receive answer (make sure mode is in degrees)

The answer should come to be roughly 58 deg.

x ≈ 58.0°

Step-by-step explanation:

Since the triangle is right use the cosine ratio to solve for x

cosx° = = , thus

x = ( ) ≈ 58.0°
