Question

Please solve it guys it's urgent

Answer 1

Answer:

Step-by-step explanation:

adjacent angles total sum=180°(adjacent angles of a parallelogram)

Let common ratio be x

7x + 5x =180°

12x=180°

x=180/12=15

1st angle=7x=7 times 15

                    =105°

2nd angle=5x=5 times 15

                      =75°

Hope this helps.

Answer 2

Hey there!

Answer:

∠ 1 = 7x = 7 * 15 = 105°

∠ 2 = 5x = 5 * 15 = 75°

Step-by-step explanation:

Given,

Let the angles be 7x and 5x.

We know,

Sum of adjacent ∠s of ||gm = 180°

7x + 5x = 180°

12x = 180°

x = 180° / 12

x = 15

Now,

∠ 1 = 7x = 7 * 15 = 105°

∠ 2 = 5x = 5 * 15 = 75°

Hope it helps You!
