Question

Find the value of x in the diagram above
​

Answer 1

Step-by-step explanation:

70°+3x+50°+x+4x = 360° [sum of ∠s around a point]

⇒8x+120° = 360°

⇒8x = 360°-120°

⇒8x = 240°

⇒x = $\frac{240°}{8}$

⇒x = 30

Answer 2

Step-by-step explanation:

It is a complete angle

3x+4x+x+50+70=360°

so,

8x= 360°-120°= ( transpose)

8x= 240°

x=240°÷8(transpose)

x=30°

similarly you can find 3x and 4x

3(30)=60°

4(30)=120°
