Question

Find the value of x​

Answer 1

Answer:

40+x+4x+3x=360

sum of all angles around a point.

so..8x=360-40

8x=320

x=40

Answer 2

Answer:

40°

Step-by-step explanation:

We know that the sum of all the angles in a point is 360 degree.

So, x + 4x + 3x + 40° = 360°

or, 8x = 360° - 40°

or, 8x = 320°

or, x = 320°/8

or, x = 40°
