y

Explanation:

Answer 2

Y. this one is similar to the above triangle.

proof :-

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 same.
