Answer:
x = 7
y = 37
Explanation:
congruent triangle LMN == PQR
Angle NLM = Angle RPQ
3x + 24 = 7x - 4
28 = 4x
x = 7
Angle LNM = Angle PRQ
2x + y = 180 - 84 - (7x - 4)
14 + y = 96 - (49 - 4)
14 + y = 51
y = 37
check answer
Angle LNM = 14 + 37 = 51
Angle NLM = 21 + 24 = 45
Angle LMN = 84
3 angles get a sum of 180
