Question

The angles of a triangle are in ratio 3 : 1 : 2 the measure of largest angle is ?
​

Answer 1

Answer:

Solution. Let x be any number such that the three angles are (3x)°, (1x)°, and (2x)°. We know, the sum of the angles of a triangle is 180°. The measure of the largest angle is 90°

Answer 2

Answer:

90⁰

Explanation:

Let the angles be 3x, x and 2x.

3x+x+2x=180⁰ (Angle sum property of triangle)

6x=180⁰

x=30⁰

Largest angle = 3x = 3×30 = 90⁰
