Triangle abc is similar to triangle xyz.    ab=9.7, bc=9.6, ac=15.1yz=118.8, find xztriangle abc is similar to triangle xyz.    ab=9.7, bc=9.6, ac=15.1yz=118.8, find xz

XZ = 186.8625.

Since the triangles are similar, the ratio of their angles is the same.  This means the ratio of BC to YZ will be the same as the ratio of AC to XZ; using this to set up a proportion,

9.6/118.8 = 15.1/x

Cross multiply:
9.6*x = 118.8(15.1)
9.6x = 1793.88

Divide both sides by 9.6:
9.6x/9.6 = 1793.88/9.6
x = 186.8625

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.

Your answer should be 1/3. i hope i could ! good luck : )
