Two angles are supplementary. They have the following measures: m∠ACB=x° and m∠BCD=26° . What is the measure of ∠ACB ?(1 point) m∠ACB= °
Supplementary angles add up to 180°. Since ∠ACB and ∠BCD are supplementary, we can set up the equation:
x + 26° = 180°
Subtracting 26° from both sides, we get:
x = 154°
Therefore, the measure of ∠ACB is 154°.
