Question

if pqr is supplementary to xyz and the measure of xyz equals 110 degree ,then what is the measure of pqr?

Answer 1

Supplementary angles add to 180, therefore we have:
pqr + xyz = 180
and we also know that xyz = 110, so we substitute and solve:
pqr + xyz = 180
pqr + 110 = 180
pqr = 180 - 110
pqr = 70
so the pqr angle is 70 degrees
