Question

the angles of the Triangles are in the ratio of 1:2:3 find the largest Triangle

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

30, 60, 90 are the angles of the triangle.

Hope it Helps..

Answer 2

well let the ratio be x
so
angle.1 = x
angle.2 = 2x
angle.3 = 3x
as sum of angles is always 180°
so
x + 2x + 3x = 180°
6x = 180°
x = 30°
so
angle.1 = x = 30°
angle.2 = 2x = 60°
angle.3 = 3x = 90°
so largest angle is 90°
