Question

Find the value of x and all the angles in the given below triangle.
​

Answer 1

Answer:

answer................... .

sum of all angle = 180°

5x-60°+2x+40°+3x-80°=180°

10x-60+40-80=180°

10x-100°=180°

10x=180°+100°

10x=280°

x=280°/10

x=28

Answer 2

angleA+angleB+angleC=180(Angle sum (5x-60)+(2x+40)+(3x-80)=180 sum

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

10x-100=180

10x=180+100

10x=280

X=280/10

X=28
