Question

If m∠BOA is 180° and m∠BOC is 110° , what is the measure of ∠COA ?(1 point)

An illustration shows three rays from a common origin point at upper O. The first ray upper O upper B is inclined to the horizontal left of upper O with an arrow at upper B. The second ray upper O upper C is inclined to the top right from upper O with an arrow at upper C. The third ray is to the horizontal right of upper O with an arrow at upper A. The angle upper B upper O upper C is labeled as 110 degrees. The angle upper C upper O upper A is marked with the curved angle symbol.$$

Since angle BOA is 180° and angle BOC is 110°, the measure of angle COA can be found by subtracting the measure of angle BOC from angle BOA.

180° - 110° = 70°

Therefore, the measure of angle COA is 70°.
