Question

in parallelogram ABCD , angleA = (4x-5) degree and angle C = (3x+10) degree. find angle A and angle B .​

Answer 1

Answer:

Being the opposite sides, A & C are equal.

So, (4x-5) = (3x+10)

=> 4x-3x = 10+5

=> x = 15

So the angle is 4x - 5 = 4×15 - 5 = 60-5=55°

So, B & D are also equal.

Their values are:-

(180°-55°)=125
