Given:
Angle = -770°
Let's find angle A which is coterminal with the given angle.
Where:
0°
Coterminal angles can be said to be angles that sum up to a multiple of 360 degrees.
The angle which measures -770 is 2 revelotions and 50 degrees:
-360 - 360 - 50 = -770
Tus, to find the coterminal angle, we have:
360 - 50 = 310°
Therefore, the coterminal angle with an angle measuring -770° is 310°.
ANSWER:
310°
