Question

An exterior angle of a triangle measures 70 degree and its interior opposite angles are in the ratio 3:4 . Find the angles of the triangle.

Answer 1

let the given angles be 3x and 4x
by angles sin property
3x+4x=180
7x=180
x=180÷7
25.174258271
3×25.174258271=75.52277
4×25.174258271=100.69703371
