HELP PLEASE !!!!!!!!!!!

To the nearest whole degree, what angle measure has a cosine of 0.9123??

Answer 1

you have to use in your calculator cos^-1 of 0.9123

your angle=24.17 or 24°

Answer 2

24

Explanation:

You can find the cosine of an angle, If you divide the length of the adjacent side by the length of the hypotenuse. Since, in this question only the value of the angle is given, we need to find out the angle that corresponds to the 0.9123, cos(x) = 0.9123.

You may use any device to do that. When you enter the value, you wil get 24.17484498. If you round it to the nearest whole degree, the result will be 24.
