Question

If two adjacent angles of a parallelogram ABCD are (5x-10) and (x+10), then find the
ratio of these angles.

Answer 1

Answer:

Please mark me as brainlist.

Step-by-step explanation:

(5x-10)+(x+10)=180 [in a parallelogram sum of adjacent angles=180]

6x=180

x=30 degrees

The angles are 5(30)-10,30+10

i.e. 140,40

Ratio is 140:40=7:2

Answer 2

Answer:

5x - 10 x + 10

=> 5x = 10 => x = 10

=> x = 10/5

=> x = 2

Therefore , the ratio of these two Angeles is

1 : 5
