Question

Sum of anlges of a triangle is 180 degrees and the angles are in ratio 1:2:3.find the measures of each angle

Answer 1

Let's denote the smallest angle as X degrees.  Then the other two angles are 2X and 3X.

 

X + 2X + 3X = 180

6X = 180

X = 30

 

It is a 30, 60, 90 triangle.

Answer 2

let angles be 1x,2x and 3x
1x+2x+3x= 180
6x=180
x=180/6
x= 30
so the angles are 30°, 60° and 90°
