Find all possible solutions for x and y such that △ABC is congruent to △DEF. △ABC: sides of length 18, 25, and 5x − 3.
△DEF: sides of length 25, 22, and 5 − y.

△ABC ≅ △DEF when x is
and y is

x = 5    y = -13

Step-by-step explanation:

5(5) - 3 = 22 and 5 - (-13) = 18

no not all of them.

step-by-step explanation:

some of them have a square base.

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
