He earns $16 per hour as shown in the figure
Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!
Use arccos...cos^-1 so
cos^-1 (0.8195)
it equals 34.96522689°
