Question

find the value of x in the figure.​

Answer 1

Answer:

Step-by-step explanation:

x +10=2x-20

x-2x= -20+10

x=-10

Answer 2

2x+20+x+10 = 180° (Linear pair as total angle will be 180° as its a straight line)

3x+ 30 = 180°

3x = 180-30

3x = 150

x = $\frac{150}{3}$

x = 50°

The value of x is 50°.
