Question

two adjacent angle of a parallelogram are 6 x - 9 degree and 13 x + 18 find the ratio of the angle​

Answer 1

Step-by-step explanation:

WE KNOW THAT SUM OF ADJACENT ANGELES OF PARALLELOGRAM IS = 180

6x-9 + 13x+15 =180

19x = 171

X = 9

1st adjacent angle of parallelogram is 45

2nd adjacent angle of parallelogram is 135

In ratio = 1:5

Answer 2

6x-9+13x+18=180(Adjacent angles are supplimentary)

19x+9=180

19x=180-9

19x=171

x=171/19

x=9

Angles Are

6x-9=6*9-9

=54-9

=45°

=63°

13x+18=13*9+18

=117+18

=135°

Ratio=45:135

=9:27

=1:3
