Question

If a pair of co-interior angles intersecting two parallel lines in the ratio 2:3 then the measure of the smaller angle is
a) 54° b) 120° c) 72° d) 136°

Answer 1

Answer:

c) 72degree

Step-by-step explanation:

2:3

.: 2x+3x= 180(cointerior angle)

5x= 180

x =36

Larger angle = 3x= 3*36=108

Smaller Angle= 2x=2*36=72
