Ksju [112]

Answer:

\triangle{XAZ} \cong \triangle{XBY} by the SAS postulate (side-angle-side)

Step-by-step explanation:

This is an overlapping triangles problem.  Try drawing them separately, essentially pulling them apart.  Mark side XY and XZ as congruent (given).

Angle X is shared by the two triangles, so angle X in triangle XAZ is congruent to angle A in triangle XBY.

hoa [83]

Sum of triangle angles = 180

smallest angle = x

second angle = 3x

third angle = x +35

180 = x + 3x + x + 35

145 = 5x

x = 29 is the smallest

the second is 87

the third is 64
