Problema Solution
two angles are supplementary. the measure of one angle is 9 degrees more than twice the measure of the other. find the measure of each angle
Answer provided by our tutors
Two angles are supplementary if they add up to 180 degrees.
Let 'x' and 'y' represent the angles
since x and y are supplementary we have:
x + y = 180
the measure of one angle is 9 degrees more than twice the measure of the other:
x = 9 + 2y
by solving the system of equations:
x + y = 180
x = 9 + 2y
we find:
x = 123 degrees
y = 57 degrees

the measures of the angles are: 123 degrees and 57 degrees.
