Answer 2

Answer:

Let one of the angle be x and the other be y.

Sum of all the angles of a triangle = 180

Therefore, 65 + x + y = 180 eq.1

Also, according to the question,

x - y = 20 eq.2

Adding eq.1 to eq.2

65 + 2x = 200

2x = 135

x = 135/2

x = 67.5

substituting the value of x in eq.2

67.5 - y = 20

y = 67.5 - 20

y = 47.5
