Question

Find a positive and a negative coterminal angle for the given angle 137°.

A) -57° and 237°
B) 257° and 377°
C) 317° and 117°
D) 57° and 217°

Answer 1

To find positive and negative coterminal angles, add or subtract multiples of 360° to the given angle. For the angle 137°, a positive coterminal angle would be 497° and a negative coterminal angle would be -223°.

Step-by-step explanation:

To find positive and negative coterminal angles, we add or subtract multiples of 360° to the given angle. For the angle 137°, a positive coterminal angle would be 137° + 360° = 497°. And a negative coterminal angle would be 137° - 360° = -223°.

Therefore, the correct answer is option A) -57° and 237°.
