Question

If two adjacent angkes of a parallelogram are (2x-3)° and (5x+15)° then the ratio of these angles is?? Please answer this question.

Answer 1

the sum of adjacent angles of parallelogram is 180
so we will add the angles which is equal to 180
Hope that this will help you

Answer 2

We Know that the sum of two adjacent angles is I80°.

So, (2x-3 ) + ( 5x+15 ) = 180°

2x-3 + 5x+15 = 180
7x - 12. = 180
7x. =180-12
x. = 168÷ 7
x. = 24


Now the two adjacent sides are- 2x-3 = 45°
5x+15= 135°



Therefore, Ratio will be 45/135
