Show work plzzz!!

Answer 1

x = 37.1003638138

Explanation:

Use cos = adjacent/hypotenuse

cos41 = 28/x

Multiply x on both sides to get it out of the denominator.

x · cos41 = 28/x · x

Now you have

x · cos41 = 28

Divide both side by cos41 to get x by itself.

x · cos41/cos41 = 28/cos41

Now divide

x = 28/cos41

x = 37.1003638138
