Question

if the sides of the triangle is equaal to 5:12:13​

Answer 1

Step-by-step explanation:

is it to find the angle

let the ratio be 5x,12x,13x

sum of all angles in a triangle is 180

therefore, 5x+12x+13x=180

30x=180

x=180/30

x=6

therefore angles =

5x=5×6=30degrees

12x=12×6=72degrees

13x=13×6=78degrees
