Question

Two angles of a triangle measure 50° and 40°. What kind of triangle is it?

Answer 1

The angles of triangle are 50,40 degrees the third angle is x. so x=180-50-40=180-90=90
As there is 90 degree in one of the angles it will be known as right angled triangle.

Answer 2

angle 1:50°
angle 2:40
angle 3:(180-90)= 90

so the triangle will be scalene triangl because in scalene triangle all angles measure are different and this statement is fulfilled in this case.......

Hope it helps...
