Question

if know pls answer it fast!!!​

Answer 1

Step-by-step explanation:

x+20+2x-20+60=180( angle sum property)

3x+60=180

3x=180-60

3x=120

x=40

x+20=60

2x-20=60

60

Answer 2

Answer:

let angle A=x+20

angle B=60

angle C=2x-20

so,

A+B+C=180

x+20+60+2x-20=180

20 se 20 cancel

x+2x+60=180

3x+60=180

3x=180-60

3x=120

x=120/3

x=40
