Question

In the given figure, find the value of x.
​

Answer 1

Answer:

x=28°

Step-by-step explanation:

In ΔABC,

<BAC+<ABC+<ACB=180°

(5x-60°)+(2x+40°)+(3x-80°)=180°

5x-60°+2x+40°+3x-80°=180°

5x+2x+3x-60°+40°-80°=180°

10x-100°=180°

10(x-10°)=180°

x-10°=180°/10

x-10°=18°

x=18°+10°

x=28°

Therefore, the value of x is 28°.

Answer 2

Answer:

The value of x is 28°

Step-by-step explanation:

5x - 60° + 2x + 40° + 3x - 80° = 180°

10x - 100° = 180°

10x = 180° + 100°

10x = 280°

x = 280°/10

x = 28°
