Question

In fig. 3, ABCD is a parallelogram. Find the measure of x and y.

Answer 1

Answer:

Step-by-step explanation:

In parrallogram,

opposite angles are equal so

3x+15 = 2x+35

3x - 2x = 35 - 15

x = 20

The sum of two alternative angles in parrallogram = 180, so

2x + 35 = 2y + 5

2x +35 - 5 =2y

By using value of x,

2 X 20 +30 =2y

40 +30 = 2y

70 =2y

70/2 = y

y = 35
