Question

Solve this please it's urgent​

Answer 1

Answer:

Angle A+angle B+ angle C=180°

5x-60°+2x+40°+3x-80°=180°

10x-100°=180°

10x=180°+100°

10x=280°

x=280°/10

x=28°

Answer 2

Answer:

X=28 degree

Step-by-step explanation:

from triangle ABC,

given

angle A=5X-60

angle B=2X+40

angle C=3X-80

sum of the angles of a triangle are 180

angle A+angle B+angle C=180

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

10X-100=180

10X=180+100

10X=280

X=280÷10

X=28
