Question

If two opposite angle of a parallelogram are (63 - 3x) degre and (4x - 7) degree ,find the angle of a parallelogram.

Answer 1

We know that Opposite angles of paralellogram are equal.

So,

63 - 3x = 4x - 7

=> 63 + 7 = 4x + 3x

=> 7x = 70

=> x = 10

First angle = (63 - 3× 10) = 63 - 30 = 33°

Second angle = 180 - 33 = 147°

Third angle = 33°

Fourth angle = 147°

Answer 2

Step-by-step explanation:

63 - 3x = 4x - 7

=> 63 + 7 = 4x + 3x

=> 7x = 70

=> x = 10

1st angle = (63 - 3× 10) = 63 - 30 = 33°

2nd angle = 180 - 33 = 147°

3rd angle = 33°

4th angle = 147°
