Answer:
Step-by-step explanation:
In order to solve this problem, we must assume the given triangles are congruent.
__
Equating expressions for the hypotenuse, we have ...
10x = 2x +8
8x = 8 . . . . . . . . subtract 2x
x = 1 . . . . . . . . . . divide by 8
Equating expressions for the bottom legs, we have ...
y +2x = 10x -y
2y = 8x . . . . . . . . add y-2x
y = 4x = 4(1) . . . . divide by 2, substitute for x
y = 4
