Answer 2

Answer:

$\huge \bold {Question}$

The angle of triangle in ratio is 3:2:1 find angle

$\huge \bold {To \: find}$

Angle of triangle

$\huge \bold {Answer}$

$1st \: side = 3$

$2nd \: side \: = 2$

$3rd \: side \: = 1$

All in ratio

Consider the number to be x

$\bold {Sum \: of \: ratio = 3x\: + 2x \: + 1x}$

Sum of angle in triangle = 180⁰

Sum in ratio = 6x

6x = 180

$x = \frac{180}{6 } = 30$

3x = 30× 3 = 90

2x = 30 × 2 = 60

1x = 30 × 1 = 30

Verification

180=90+60+30

180= 180

Hence proved
