Isuck at math. △abc△abc is similar to △xyz△xyz by the aa similarity postulateaa similarity postulate . the measure of ∠a∠a is 39º and the measure of ∠c∠c is 24º. what is m∠ym∠y?

180 degrees in a triangle. subtract the 2 know angles to get the third.
180-39-24=117

If △ABC is similar to △XYZ, the angles have the same degree measure.
Since m∠A is 39° and m∠C is 24°, and the total measure of the inner angles is;
(n - 2)180° = (3 - 2)180° = 180°,
180° = m∠A + m∠B + m∠C
180° = m∠B + 39° + 24°
m∠B = 117°
But because △ABC is similar to △XYZ, m∠B = m∠Y;
m∠B = m∠Y = 117°

than do 23.50 times 18 and then divide your answer by 100 than you will get x.
