Question

Find length of AC? Help please

Answer 1

D

Explanation:

cos(theta) = B/H

cos(51)= AC/58

AC=36.5

Answer 2

36.5 = AC

Explanation:

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

cos theta = adj side/ hypotenuse

cos A = AC / AB

cos 51 = AC /58

58 cos 51 = AC

36.50058 = AC

Rounding to the nearest tenth

36.5 = AC
