Question

the angles of a triangle are in the ratio of 1: 3: 5. find the measure of each angle of the triangle​

Answer 1

x+3x+5x=180°

9x=180°

x=180/9°

x=20°

Angle1=20°

Angle 2=2×20°=60°

Angle 3=5×20°=100°

Hope this helps!

Answer 2

Here's your answer! ❤

A triangle have 3 sides.

The sum of all the three sides is 180°,

$let \: the \: unknown \: angles \: be \: x \\ 1x : 3x : 5x \\ 1x + 3x + 5x = 180 \\ 9x = 180 \\ x = \frac{180}{9} \\ x = 20 \\ first \: angle \: = 20 \times 1 = 20 \\ second \: angle \: = 20 \times 3 = 60 \\ third \: angle \: = 20 \times 5 = 100 \\ angle \: 1 = 20° \\ angle \: 2 = 60° \\ ange \: 3 = 100° \: \\ 20° + 60° + 100° = 180°$
