Question

two anglesof a triangleare in the ratio 2:3 and its third angle is 80° find the other two angles of the triangle
​

Answer 1

Step-by-step explanation:

let the angle be x

then sum of three angle =180°

2x+3x+80°= 180°

5x= 180°- 80°

5x = 100°

x= 100°/5

x= 20°

so the angle 2x = 2×20°= 40°

other Angle 3x= 3× 20° = 60°
