Question

if the angle of a triangle are in ratio5:3:7 then find the smallest angle
​

Answer 1

Answer:

let the angles be 5x,3x and 7x.

so, according to angle sum property... 15x= 180.

so,X= 180÷15.

so,find the value from there.

ok?

Answer 2

Answer:

36

plz mark as brainliest

Step-by-step explanation:

the sum of a triangle = 180

the ratio is = 5:3:7

take x as the common factor such that (5 x x) + ( 7 x x) +( 3 x x) = 180

therfore

=> 5x+7x+3x=180

15x=180

x=180/15

x=12

the smallest angle = 3 x 12 = 36
