Answer 2

Answer:

$opposite \: angles \: of \: \\ parallelogram \: are \: equal$

So,

(63-3x)° = (4x-7)°

=> -3x-4x = -7 -63

=> -7x = -70

=> 7x = 70

=> x = 70/7 = 10

Now,

(63-3x)° = 63-30 = 33°

and (4x-7) = 40-7 = 33°

Now,

Let, other two angles = x (as they are equal )

x+x+33+33 = 360

=> 2x +66 = 360

=> 2x = 360-66

=> 2x = 294

=> x = 294/2= 147

Hence,

All angles = 33°,147°,33° and 147°.
