Answer 1

Answer:

angle of a triangle is 360 degree

Answer 2

Let the other two angles be x and y; then,

x-y = 25°

or, x = 25° + y ......(1)

And, x +y = 180° - 65° = 115°

or, x = 115° - y .......(2)

Substituting the values of (1) and (2); we get,

25°+y=115° - y

or, 2y = 90°

or, y = 45°

or, x = 70°

Hence, the correct option is (C)
