Question

can someone please solve this​

Answer 1

Answer:

As it is linear pair of angles and linear angles are supplementary,

6x+30+4x=180

10x+30=180

10x=180-30

10x=150

x=150/10

x=15

Answer 2

Since the angle is a straight line the whole is = 180

So,

4x+6x+30=180

10x+30=180

10x=180-30=150

x=150/10=15

Checking,

4x15+6x15+30=180 Hence Proved x=15
