Question

figure line l and line m are parallel, then find the measure of angle 'a 'and angle ' b' ​

Answer 1

Step-by-step explanation:

angle A = 80° ( vertically opposite angles are equal )

angle B = we know that co- interior angles on the Same side of transverse are supplementary.

hence, a+b = 180

or 80 + b = 180

or b = 180-80

hence, b = 100°

correct answer is a= 80, and b= 100
