Question

draw triangle ABC with BC=6cm and angles are in ratio 3:4:5

Answer 1

let the three angles be 3x,4x and 5x
3x+4x+5x= 180 degree ( sum of all the angles of a triangle)
= 12x=180 degree
= x = 180÷ 12=15 degree
3x= 3×15=45 degree
4x=4×15=60 degree
5x=5×15=75 degree

Now u can draw the triangle.
