Question

In a parallelogram ABCD,if angle A =(2x+25) and angle B=(3x-5). Find the value of x

Answer 1

in a parallelogram sum of adjacent angles are supplementary
A+B =180
2x+25+3x-5=180
5x+20=180
5x=180-20
5x=160
x=160/5
x=32

Answer 2

angle A +ag B=180 (corresponding angle are 180º.)
2x+25+3x-5=180º ( angle A=2x+25 and angle B=3x-5)
5x+20=180º
5x=(180-20)º
x=(160÷5)º
x=32º.
