Question

. In the given figure, find x.​

Answer 1

Answer:

x is 28°

Step-by-step explanation:

Sum of angle of triangle = 180°

5x - 60° + 2x + 40° + 3x - 80° = 180°

10x - 100° = 180°

10x = 180° + 100°

10x = 280°

x = 280°/10

x = 28°

Answer 2

Step-by-step explanation:

In ∆ABC

Angle A=5x-60°,Angle B=2x+40°,Angle C=3x-80°

Angle A+Angle B+Angle C =180°...(Sum measure all the angle of triangle is 180°)

5x-60°+2x+40°+3x-80°=180°

10x-100°=180°

10x=180°+100°

10x=280°

x=280°/10

x=28
