Q. Find the measure of a negative angle coterminal with 60∘. ____∘
Subtract 360° from 60°: To find a negative angle coterminal with 60°, subtract 360° from 60° because coterminal angles are separated by full rotations, which are 360°.Calculation: 60°−360°=−300°.
Check range for −300°: Check if −300° is within the range of a full negative rotation −360°.Since −300° is greater than −360°, it is a valid negative coterminal angle for 60°.
