Question

These two triangles are congruent by the Hypotenuse-Leg Theorem.

Answer 1

Answer:

$y = - 2$

Step-by-step explanation:

Given that the 2 triangles are congruent based on the Hypotenuse-leg theorem, this implies that:

$x - y = x + 2$ , and $2x - y = 4x + 2y$

Using the expression, $x - y = x + 2$, solve for y:

$x - y - x = x + 2 - x$

$- y = 2$

$y = - 2$
