Question

In a parallelogram ABCD angleA=(2X+10)°and Angle c= (3x-20)° . find the value of x

need full explanation?

Answer 1

Given - ABCD is a parallelogram

A=2X+10

C=3X-20

To find- X

Solution- A =C ( opposite angles of parallelogram are equal)

2X+10=3X - 20

2X-3X=-20-10

-X=-30

X=-(-30)

X=30°

Answer 2

Heya !

ANSWER :-
—————————

Since , opposite angles in a Paralellogram are equal , given that /_A and /_C .

So ,

(2x + 10)° = (3x - 20)°

=> 2x + 10 = 3x - 20

=> 2x - 3x = - 10 - 20

=> - x = -30

( Both side minus gets cancelled so x = 30 )

Therefore ,

= x = 30

Ans : The value of 'x' is 30 .
