Question

the angles of a triangle ate in the ratio 2:3:7 then the largest angle is?

Answer 1

let the angles be 2x 3x 7x
A to Q
2x+3x+7x=180.(sum of angles of triangle.is 180°)
x=15
so ,largest angle is 105°

Answer 2

First, assume that sum of the angles of triangle = 180.

Make the equation like 2X + 3X+ 7X = 180.

From that equation, the largest angle is 7 times greater than that of the smallest angle. So, 12X = 180. X = 15.

Assume X value is to the largest angle 7X. 7X = 7 X15 = 105.
