sum of two angles of a triangle is 85° and their difference is 25°. – InterviewSolution

1.

sum of two angles of a triangle is 85° and their difference is 25°. Find all three angles fThetriangle.

Answer»

let x and y be two anglesx+y=85x-y=25adding both equations2x=110x=55y=x-25=55-25=30let z be third anglethen z=180-(x+y)=180-85=95
