Question

Find the measures of the indicated angle to the nearest degree.​

Answer 1

You need to use trigonometry to find out the angle.

We use the cosine rule here.

Assuming our angle to be 'x',

cos x = adjacent / hypotenuse

here, adjacent = 35, hypotenuse = 38

cos x = 35/ 38

x = cos^-1 35/38

x = 22.9°
