Question

In a triangleABC,angleA+angleB=65,angleB+angleC=140.Find the mearure of each angle of the triangle

Answer 1

We know,

AngleA+AngleB+AngleC = 180°

=> 65°+AngleC = 180°

=> AngleC = 180°-65°

=> AngleC = 115°

Again,

AngleB+AngleC = 140°

=> AngleB+115° = 140°

=> AngleB = 25°

You cqn find Angle A easily
