Question

In a triangle angle A is 5x-60, B=2x+40 and C=3x-80​

Answer 1

By angle sum property we know that A+B+C=180

Putting A,B and C :

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

10x -100 = 180

10x = 280

x = 28

Answer 2

Answer:

x=16

Step-by-step explanation:

angle A = 5x+60

angle B = 2x+40

angle C = 3x-80

sum of angles of a triangel = 180

A+B+C= 180

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

10x+20=180

10x=160

x=160/10

x=16
