Question

From the adjecent figure the value of x is 30º. Justify ? ​

Answer 1

Step-by-step explanation:

We know that, angles of a linear pair sums up to 180°.

According to question,

(3x+20)+(2x-20)+x = 180°

3x+20+2x-20+x = 180°

6x = 180°

x = 180/6 = 30°

Hence, proved that the value of x here is 30°.
