Question

V. In a parallelogram ABCD, ∠A = ( 6 X – 17 )° and ∠C = ( X + 63 )°, then ∠B = ……..​

Answer 1

Answer:

We have,

In parallelogram ABCD

∠A=(6x−17)

o

and∠C=(x+63)

o

Find the value of ∠A

Then, We know that

∠A=∠C ∴It is aparallelogram

6x−17=x+63

6x−x=63+17

5x=80

x=16

o

Then,

∠A=6x−17

∠A=6×16−17

∠A=96−17

∠A=79

o

Hence, this is the answer.

Answer 2

Answer:

in parallelogram opposite angle are equal

angle A= angle C

6x-17=x+63

5x=80

x=16

angle A=96-17

= 79

angle A and angle B are on the same side of parallel

angleA+angle B=180

angle B=180-79

=101
