Question

The 2 adjacent angles of a quadrilateral are (2x-2) degree and (5x+7)degree.Then find the ratio of these angles.

Answer 1

Answer:

11:2

Step-by-step explanation:

as they are quadrilateral adjacent angles will be = 180 degree

2x-2+5x+7=180

7x+5=180

7x=175

x=175/7

x=25 degree

one angle = 2*25-2 = 50-2 = 48 degree

other angle = 5*25+7 = 125 + 7 = 132 degree

ratio = 11:2
