Question

Q1) 3 sides of a triangle are on ratio 1:2:3

with step ​

Answer 1

Answer:

30,90,60

Step-by-step explanation:

1:2:3 let it be x

1x+2x+3x =180

6x=180

x=180/6

x=30

it means 1 =30

2x= 180

x=180/2

x=90

it means 2 =90

3x=180

x=180/3

x=60

it means 3=60

Answer 2

Given,

The three angles of a triangle are in the ratio $1:2:3$

Let the first angle be $1x$

Let the second angle be $2x$

Let the third angle be $3x$

As we know that the sum of three angles of a triangle is $180^{0}$

$1x+2x+3x=180^{0}$

$6x=180$

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

$x=30$

The first angle is $30^{0}$

The second angle is  $2x=2(30)$

The second angle $60 ^{0}$

The third angle is $3x=3(30)$

The third angle is $90^{0}$

Therefore, the three angles are $30^{0}, 60^{0}, 90^{0}$
