Find the missing length. The triangles in each pair are similar.

Step-by-step explanation:

Question 1:

Triangles EFG and JKL are similar.

Therefore GE/LJ = EF/JK.

=> 35/7 = ?/13, ? = 65.

Question 2:

Triangles PQR and JKR are similar.

Therefore QR/KR = PR/JR.

=> 169/65 = ?/65, ? = 169.

Question 3:

By Side-Splitter Theorem,

RE/RD = RT/RS.

=> 50/60 = 70/?, ? = 84.

Question 4:

By Side-Splitter Theorem,

KC/KB = KM/KL.

=> ?/65 = 121/143, ? = 55.

The answers are 65, 169, 84 and 55 respectively.
