Option B:
x = 4 and y = 8
Solution:
The two triangles are congruent by HL theorem.
If two triangles are congruent, then the corresponding sides also congruent.
2x - 5 = y - 5
Add 5 on both sides
2x - 5 + 5 = y - 5 + 5
2x = y ------- (1)
Similarly,
y - 3 = x + 1
Add 3 on both sides.
y - 3 + 3 = x + 1 + 3
y = x + 4 ------- (2)
Equate (1) and (2), we get
2x = x + 4
subtract x from both sides.
2x - x = x + 4 - x
x = 4
Substitute x = 4 in (2), we get
y = 4 + 4
y = 8
Therefore x = 4 and y = 8.
Option B is the correct answer.
