Question

The measure of three angles of a triangle are in a ratio 5:3:1 find the measure of three angles

Answer 1

Answer:

Let the measure of three anglesof the triangle be (5x)°, (3x)° and x°.

Atq,

$\: \: \: \: \: \: \: \: 5x +3x + x = 180$

$= > 9x = 180$

$= > x = \frac{180}{9}$

$= > x = 20$

Hence, the measure of three angles are (5×20)° = 100°,(3×20)° = 60° and 20°
