Question

Pls tell the answer fast

Answer 1

Explanation:

1. 5x-60+2x+40+3x-80=180°

2. 10x=280°

3. x=28°

4. Angle A=80, B=96 nd angle C=4

Answer 2

angle (A) = 80° ,, angle (B) = 96° and angle (C) =4°

Explanation:

Using angle sum property of a ∆ we get

A+B+C= 180°

(5x-60°) + (2x+40°) + (3x-80°) =180°

by solving we have

10x-100°=180°

10x=280°

[x=28]

Now

A=5x28-60°= 80°

B=2x28+40°= 96°

C=3x28-80°= 4°

this is ur answer !!! hope it helps
