Postulate 17 (AA Similarity Postulate): If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar. http://www.cliffsnotes.com/math/geometry/similarity/similar-triangles

unklerhaukus · Answer

Use   the sum of the angles in the first triangle must equal to 180°, and hence find C,

unklerhaukus · Answer

50° + 33° + C° = 180°

solve the equation for C°
