Question

Which negative angle is equivalent to an 85° angle?
A. An angle measuring -265º.
B. An angle measuring -85°
C. An angle measuring -95°
D. An angle measuring -275°​

Answer 1

Given :  85° angle

To Find : Which negative angle is equivalent to an 85° angle?

A. An angle measuring -265º.

B. An angle measuring -85°

C. An angle measuring -95°

D. An angle measuring -275°​

Solution:

360° is complete circle

Adding or subtracting 360° or multiple of 360° result in same angle

negative angle is equivalent to an 85° angle = 85° - 360°

= - (360° - 85°)

= - (275°)

= -275°​

An angle measuring -275°​  is equivalent to an 85° angle
