which triangle is similar to the triangle above?
( explain how you got your answer you)

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.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
