Question

Two angle of a triangle are in the ratio 4:5 if one angle is 10 degree greater than second angle find the angle.

Answer 1

let first angle be x degree

and the second angle be x+10 degree

by given condition

x÷x+10=4÷5

5x=4 (x+10)

5x=4x+40

5x-4x=40

x=40

first angle = 40 degree

second angle=50 degre
