do you see that the triangle in the rectangle are isosceles triangles, because the diagonals in the rectangle has the same length and they divide each other therefore the base angles are equal

yeah

then you can calculate the purple angle and you get 140 because it is an Supplementary Angle what that means that if you have 2 angles on a straight line if you add them they should equal 180.
and the orange angle is 40 because it is an vertical Angle (Angles opposite each other when two lines cross. They are always equal.)

your welcome. if you get stuck in questions like these try to read the properties for the shape and for the properties for the angles.
