Question

Hi all, pls refer the above diagram and help me with this sum.

Answer 1

Step-by-step explanation:

Sum of all angles at common vertex = 360°

3x + 50° + x + 4x + 70° = 360°

8x + 120° = 360°

8x = 360 - 120 = 240°

x = 30°

Answer 2

Answer:

here the sum of the angles is 360 degree

besause the lie surrounding a point

so 360= (70+50+3x+4x+x)

=120+8x

8x=360-120

=240

x=240/8

=30
