The angle in a triangle are in
the ratio 1:2:3 the
sum of all the
angles of triangle is 180 find the individual angle
​

Answer 1

Question :-

The angle in a triangle are in the ratio 1:2:3 the sum of all the angles of triangle is 180 find the individual angle.

Answer :-

The sum of all the angles of a triangle = 180° .

Therefore the angles are as follows ⤵

$x + 2x + 3x = 180 \\ \\ 6x = 180 \\ \\ x = \frac{180}{6} \\ \\ x = 30 \\ \\ The \: individual \: angles \: are \: as \: follows \: \\ \\ x = 30 \\ 2x = 60 \\ 3x = 90</p><p>$

Answer 2

Answer:

let the proportion of ratio be x

then first side =x

second =2x

third=3x

Area=[GIVEN]

we know, area of triangle = one side + second side+ third side

x+2x+3x=180

6x=180

x=180/6

x=30

So, first side =30

second side= 30×2=60

third side=30×3=90
