Your question is incomplete. The complete question is attached down

Answer:

JM = 20 units

Explanation:

∵ Hexagon RSTUVW is similar to hexagon JKLMNP

∴ The corresponding sides and diagonals have a constant ratio


(RS)/(JK)=(ST)/(KL)=(TU)/(LM)=(UV)/(MN)=(VW)/(NP)=(RW)/(JP)=(RU)/(JM)

∵ ST = 6 units

∵ KL = 10


(ST)/(KL)=(6)/(10)

- Simplify it by dividing up and down by 2


(ST)/(KL)=(3)/(5)


(ST)/(KL)=(UR)/(JM)

∵ RU = 12 units


(3)/(5)=(12)/(JM)

- By using cross multiplication

∴ JM × 3 = 5 × 12

∴ 3 JM = 60

- Divide both sides by 3

∴ JM = 20 units

RU and JM are diagonals. Given ST= 6, KL = 10, and RU= 12, find JM Please answer as-example-1
