Two angles are supplementary with measures ACB goes for XNBCD equals 6X +50. What is the measure of a CB
If angles ACB and XNBCD are supplementary, then their measures must add up to 180 degrees.
So, 6X + 50 + CB = 180.
Now, to find the measure of CB, we need to isolate it on one side of the equation.
Subtract 6X + 50 from both sides to get:
CB = 180 - (6X + 50).
CB = 180 - 6X - 50.
CB = 130 - 6X.
Therefore, the measure of CB is 130 - 6X.
