Question

Two opposite angles of a parallelogram angle a=(6x _17) &angle c=(x+63) . Find the measure of angle a

Answer 1

Opposite angles of paralleogram are equal

So, angle A = angle C

6x- 17 = x+63

6x-x = 63+17

5x = 80

X = 80/5

X = 16

Putting value of X in angle A

Angle A = 6x- 17

= 6*16-17

= 96-17

= 79°
