To find the measure of ∠ACB, we need to set up the equation that states the two angles are supplementary.
Supplementary angles add up to 180 degrees, so we have:
m∠ACB + m∠BCD = 180
Substitute the given measures of m∠ACB and m∠BCD into the equation:
4x + (6x + 50) = 180
Combine like terms:
10x + 50 = 180
Subtract 50 from both sides:
10x = 130
Divide by 10:
x = 13
Now, substitute x back into the measure of ∠ACB:
m∠ACB = 4(13) = 52 degrees
Therefore, the measure of ∠ACB is 52 degrees.
Two angles are supplementary with measures m∠ACB=4x° and m∠BCD=(6x+50)° . What is the measure of ∠ACB ?(1 point)
