Question

The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the

largest angle?

Answer 1

84°

Explanation:

Let the measures of the triangle be 5x, 7x, 3x.

By interior angle sum postulate of a triangle.

5x + 7x + 3x = 180°

15x = 180°

x = 180°/15

x = 12°

7x = 7*12°= 84°

Measure of the largest angle = 84°
