Question

the measure of the angles of a triangle are in th ratio 1:2:3. find the angles​

Answer 1

Answer:

first side=1x

second side=2x

third side=3x

1x+2x+3x=180

6x=180

x=180/6

x=30

first side = 1×30=30

second side =2×30=60

third side =3×30=90

please mark me as brainliest

Answer 2

Sum of the measures of all angles = 180°

Let us take the measures of all angles as

$1x + 2x + 3x$

So,

Sum of all angles = 180°

1x + 2x + 3x = 180°

6x = 180°

x = 180 ÷ 6

x = 30

Now,

the measure of 1st angle = ( 1 × 30 ) 30°

measure of 2nd angle = ( 2 × 30 ) 60°

measure of 3rd angle = ( 3 × 30 ) 90°
