Answer:

  • x = 2
  • ∠R = 85°
  • y = 3

Explanation:

Given quadrilaterals JKLM and NPQR are similar with K=100°, M=85°, JK=12, LM=(5y+1), MJ=20, RN=10, NP=(x+4), PQ=7, QR=8, you want to identify the true statments.

Relations

Corresponding angles are congruent, so we have ...

∠K≅∠P = 100°

∠M≅∠R = 85°

Corresponding sides have the same ratio. The larger : smaller ratio here appears to be 2 : 1.

JK : NP = 12 : (x+4) ⇒ x+4 = 6 ⇒ x = 2

KL : PQ = ? : 7 ⇒ KL = 14

LM : QR = (5y+1) : 8 ⇒ 5y+1 = 16 ⇒ y = 3

MJ : RN = 20 : 10 . . . . . establishes the ratio for the others

The true statements are ...

  • x = 2
  • ∠R = 85°
  • y = 3

Additional comment

It can be helpful to write a list of the specific correspondences (based on the similarity or congruence statement).
