Answer:

Y

Step-by-step explanation:

Similar triangles have the same angles measures and side lengths that are proportional.  Since side lengths aren't given, you need to look at the measure of the angles.  The sum of all the angles of a triangle is 180°.  The given triangle has an angle of 20° and 88°, so the remaining angle is: 180 - 20 - 88 = 72°.  The only other triangle with the same angles is Y.

Triangle Y is similar to the above triangle.

How to find similar triangles?

If we subtract the sum of two angles in triangle Y from 180° we get 88°. which is the third angle of the above triangle.

and sum of 88° + 20° = 108°

by angle sum property, we can find it's another angle.

= 180° - 108°

= 72°

hence, it's proved that both triangles are the same.
