how to find the angles given below. what are the steps you need to find supplementary, complementary , opposite ,corresponding and alternate angle and also scalene triangle? I seriously need help with these angles and i have asked my teacher many times but.....lets just maybe someone here can help me understand it better.

Supplementary angles equal 180 degrees, so they make a straight line. Complementary angles equal 90 degrees, so they make a right angle. Opposite angles are across from each other. Alternate angles can be interior, which make a z shape, or exterior, which are opposite of the angles that make a z. Scalene triangles have all unequal sides and angles. 
It might help to look up pictures of these.
