Question

Find the values of a and b

Answer 1

The values of a and b are as follows :
A=109
B=65

Answer 2

a = 115, b = 71

Explanation:

The figure has one pair of parallel sides and is a trapezium.

Using a property of trapeziums

• each lower base angle is supplementary to the upper base angle on the same side.

a = 180 - 65 = 115

b = 180 - 109 = 71
