Question

prove that measure of all angle of a triangle is 60 degree​

Answer 1

Answer:

let the angles=x

x+x+x =180°

3x= 180°

x=180/3

x=60° Ans

please follow me

Answer 2

Let all the angles be x degree

we know sum of angles of a triangle is 180 degree.

$x + x + x = 180 {}^{0}$

$3x = 180 {}^{0}$

$x = \frac{180}{3}$

$x = 6 0{}^{0}$

$so \: \: sum \: \: of \: \: angles \: \: is \: \: 60 {}^{0}$
