Question

What is the measure of an angle whose measure is 32 degree less than it's supplementary?
a) 148 degree
b) 60 degree
c) 74 degree
d)55 degree
​

Answer 1

Answer:

Let the measure of the required angle be x∘. Then, measure of its supplement =(180-x)∘. ∴(180-x)-x=32⇒2x=148⇒x=74. Hence, the measure of the required angle is 74∘.
