Question

One angle of the abc is 40 degree if the difference of the other two angles is 30degree find the larger of the other two angles

Answer 1

Answer:

let the angle be a, b, c

a = 40

b - c = 30, it means c = b - 30

We know a + b + c = 180

40 + b - 30 + b = 180

2b = 170

b = 85

and c = 55

So larger angle is 85.
