Question

An angle measures 154° less than the measure of its supplementary angle. What is the
measure of each angle?
and
0

Answer 1

Answer:   13 degrees and 167 degrees

====================================================

Work Shown:

x = unknown angle

y = supplementary to angle x

x = y - 154

x+y = 180 since they are supplementary

y-154+y = 180

2y-154 = 180

2y = 180+154

2y = 334

y = 334/2

y = 167

x = 180-y = 180-167 = 13

The two angles are 13 degrees and 167 degrees.
