Question

the measure of angle of triangle are in ratio 4:11:15 what type of triangle it is

Answer 1

Sum of all angles of a triangle=180 . Let First angle be 4x ,Second angle be 11x,Third angle be 15x .4x+11x+15x=180 .30x=180 .x=6 .First angle=24,second angle=66,third angle=90. This is scalene triangle because all the angles are not equal.
