Question

In the given figure find the value of .

​

Answer 1

Step-by-step explanation:

angle A+angleB+angle C= 180degree

Let,

Angle A= 5x+60degree

Angle B=2x+40degree

Angle C=3x-80degree

So, (5x+60)+(2x+40)+(3x-80)=180

5x+2x+3x+60+40-80=180

10x+100-80=180

10x=180-20

10x=160

x=160/10

x=16

so the value of 'x' is 16

Answer 2

Yes it is right X=16
