Question

In the given figure find the value of x

Answer 1

Answer

Since it is a triangle, the sum of all angles will be 180°.

So,

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

$10x - 100 = 180$

$10x = 280$

$x = \frac{280}{10}$

$x = 28$

So the value of x is:-

$\huge\boxed{x=28°}$

Answer 2

Step-by-step explanation:

5x-60°= A

2x+40° = B

3x-80° = C

A+B+C= 180°

5x-60° + 2x+40° + 3x -80°= 180°

5x+2x+3x+(-60°+40°-80°)=180°

10x + (-100°)=180°

10x-100°=180°

10x= 180°+100°

10x = 280°

x= 280° ÷10= 28°
