Q. Find the measure of a negative angle coterminal with 130∘. ____∘
Subtract 360° from 130°: To find a negative angle coterminal with 130°, we subtract 360° from 130° because coterminal angles are separated by full rotations, which are 360°.Calculation: 130°−360°=−230°.
Check range for −230°: Check if −230° is within the range of a negative full rotation (−360° to 0°).−230° is within this range, so it is a valid negative coterminal angle.
