Question

prove that the sum of three angle of traingle is 180°

Answer 1

x+x+x=180
3x=180
x=180÷3
x= 60
therfore each angle of triangle is 60
60+60+60=180
hence proved

Answer 2

Hello friend this is your answer...

Consider the three angles of a triangle as x, so

x+x+x=180°
3x=180°. >>> 1
x=60°
If u put the value if x in 1 you get
3x60° =180°


Hence proved!!

Hope it helps
