If △XYZ ≅ △LMR, then m + x + p = _________________.

Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 9.
Given that
If △XYZ ≅ △LMR, then m + x + p = _________________.⇒ XY = LM,
⇒ 2m + 1 = 5
⇒ m = 2
Similarly, YZ = MR
⇒ 2p + 2 = 8
⇒ p = 3
Similarly, ZX = RL
⇒ 7 = 2x - 1
⇒ x = 4
Hence, the value of m + p + x = 2 + 3 + 4 = 9
