Question

Pls explain in full method not in one word ​

Answer 1

Answer:

90°

Step-by-step explanation:

In parallelogram adjacent angles have their sum as 180(corresponding angles)

so S+P=180

2a = 180

a=90

Answer 2

Answer:

A=90

Step-by-step explanation:

In a parallelogram, consecutive angles are supplementary.

That is,

‹P+‹S=180°

= a-b+a+b= 180

= a+a-b+b= 180

We can cancel the b,

=a+a=180

=2a=180

= a = 180/2

=90

Hence, a = 90
