Anurag Tiwari 8 years, 1 month ago

This is a parallelogram so the oppo. Angles are equal this. (4x-7) = (63-3x) 4x+3x = 63+7 7x = 70 x = 70/7 x= 10 So (4x-7) = 33° now as we know oppo. Angles are equal so (63-3x) is also 33° Now in a parallelogram sum of co-interior angles is 180° so 33°+Angle 2 = 180° Angle 2 = 180-33 = 147. Now angle 2 is equal to angle 4 so both are 147°. If you have any more questions post them I will certainly reply.
