Question

If ABCD is a parallelogram, mZA = x° and mZD = (2x - 3)º, find the
value of 'x'.

Answer 1

x = 61

Explanation:

Angles A and D are consecutive interior angles of a parallelogram.

Consecutive interior angles of a parallelogram are supplementary.

m<A + m<D = 180

x + 2x - 3 = 180

3x - 3 = 180

3x = 183

x = 61
