Answer:
x = 4, y = 8
Explanation:
For the triangles to be congruent by the HL theorem
Then the hypotenuse and legs must be congruent , that is
x + 1 = y - 3 โ (1)
2x - 5 = y - 5 โ (2)
Subtract (1) from (2) term by term to eliminate y
2x - x + (- 5) - 1 = y - y + (- 5) - (- 3) , that is
x - 6 = - 2 ( add 6 to both sides )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
4 + 1 = y - 3
5 = y - 3 ( add 3 to both sides )
8 = y
