Q. Find the measure of a negative angle coterminal with 10∘. ____∘
Subtract 360° from 10°: To find a negative angle coterminal with 10°, we subtract 360° from 10° because coterminal angles are separated by full rotations, which are 360°.Calculation: 10°−360°=−350°.
Check Validity of −350°: Check if −350° is within the range of a full negative rotation from the positive angle 10°. Since 10°−360°=−350°, it is a valid negative coterminal angle.
