Question

The angles of triangle are x,y and 40 the difference between the two angles xand y is 3o find x,y

Answer 1

x-y = 30

x = y + 30

As we know that sum of angles in triangle is 180

x + y + 40 = 180

x + x + 30 + 40 = 180

2x + 70 = 180

2x = 180 - 70 = 110

x = 110/2 = 55

Answer:

x = 55

y = 55 + 30 = 85
