Question

the measure of angle of triangle are x degree 2x degree and 3x degree

Answer 1

x + 2x +3x = 180 degree(angle sum property of triangle)
6x = 180 degree
x = 180/6
x=30degree
2x = 2x30 = 60 degree
3x = 3x30 = 90 degree

Answer 2

hlo mate

here is your answer.

__________________

The total measure of a triangle is 180 degree.
=>x+2x+3x=180

=>6x=180

=>x=180÷

=>x=30

The angles are -:
*x=30
*2x=2×30
=60
*3x=3×30
=90
......
=>30 + 60 +90
=>180
$<b> hence proved </b>$
