Question

I need number 15. The very bottom in bold letters.

Answer 1

41°

Explanation:

Since a perpendicular angle is 90° and the guy has the pole lifted 49° already, the pole needs to be lifted 41° more so that 49+41=90. You would solve this by 90° - 49°= 41°.

Answer 2

41 degrees

Explanation:

If the pole is perpendicular to the ground, the angle it creates is 90 degrees. Barry has already lifted it 49 degrees, so

90 - 49 = 41

It must be lifted another 41 degrees.
