The ratio of the angle measures in a triangle is 2: 4: 5: 7 it's perimeter is 36 m what is the length of the shortest side

1. let the sides be 2x 4x 5x and 7x

since the perimeter is 36

therefore some of sides = 36

2x + 4x + 5x + 7x = 36

18 x=36

x = 2

shortest side = 2x = 4m

longest side = 7x = 14m

2. sum of angle = 180

let angles be 5x 12x and 19x

5x+12x+19x=180

36x = 180

x = 5

smallest angle = 5x = 25

largest = 19x = 95
