Question

In ABC, Angle A : Angle B : Angle C = 2:3:5, than angle at b is

Answer 1

Given

Ratio of angles of∆

A:B:C = 2:3:5

Solution .

By interior angle sum property

A + B + C = 180°

2x + 3x + 5x = 180°

10 X = 180°

x = 180/10

x = 18°

Measure of <B = 3 × 18

angle B = 54°

Hope it helps ♥

Answer 2

Answer:

Angle A (ratio -2) =36°

Angle B (ratio-3) =54°

Angle C (ratio-5) =90°

Step-by-step explanation:

add all ratio

2+3+5=10

divide it from the total degree of angle(180°-sum of all the angles inside a triangle )

×=18

apply to the ratio..

18x2=36°

18x3=54°

18x5=90°
