Question

two adjacent angles of a parallelogram are (3x+20) and (2x+10) yhen the value of x is

Answer 1

3x+20+2x+10=180
5x+30=180
5x=150
X=30

Answer 2

Answer:

The required value of x is 30°.

Step-by-step explanation:

Given:-

The two adjacent sides of a parallelogram are (3x + 20) and (2x + 10).

To find:-

The value of x.

Step 1 of 1

As we know,

The sum of the two adjacent sides of a parallelogram is 180°.

According to the question,

The two adjacent sides of a parallelogram are (3x + 20) and (2x + 10).

So,

(3x + 20) $+$ (2x + 10) = 180°

Collect the like terms and then add them as follows:

3x + 2x + 20 + 10 = 180°

               5x + 30 = 180°

                       5x = 180 - 30

                       5x = 150°

                         x = 30°

Therefore, the required value of x is 30°.
