Question

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

Answer 1

`y = - 2`

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`
