Two angles of supplementary and have measures M angle ABC equals 15° and M angle CBD equals X what is the value of M angles CBD

1 answer

Since the angles are supplementary, the sum of their measures is 180 degrees. Therefore, we have the equation:

M angle ABC + M angle CBD = 180 degrees

Substituting the given values, we have:

15 degrees + X = 180 degrees

To find the value of M angle CBD (X), we can solve this equation:

X = 180 degrees - 15 degrees
X = 165 degrees

Therefore, the value of M angle CBD is 165 degrees.
