Set up a proportion based on the triangle side lengths. I chose to put the smaller ones over the bigger ones:
Then cross multiply to get 1344-42x = 6x
Add 42x to both sides to isolate the x changing the equation to 13444 = 48x
Divide both sides by 48 to get x = 28

Given:
Two coins are tossed.
To find:
1. P(H on first coin)?
2. P(H on second coin)?
3. List the paired outcomes for tossing two coins.
4. How many ways are there for two coins to land?
5. What is P(HH)?
Solution:
If a a coin is tossed, then we have to possible outcomes, i.e., heads (H) and tails (T).
It is given that two coins are tossed.
1. The probability of getting a heads on first coin is:
2. The probability of getting a heads on second coin is:
3. If two coins are tossed, then the total possible outcomes are:
4. The number of ways for two coins to land is 4.
5. The probability of the heads on both tosses is:
Therefore, the required solution are:
1.
2.
3. List of possible outcomes is .
4. Number of possible outcomes is 4.
5.

Answer:
JM = 20 units
Step-by-step explanation:
∵ Hexagon RSTUVW is similar to hexagon JKLMNP
∴ The corresponding sides and diagonals have a constant ratio
∴
∵ ST = 6 units
∵ KL = 10
∴
- Simplify it by dividing up and down by 2
∴
∵
∵ RU = 12 units
∴
- By using cross multiplication
∴ JM × 3 = 5 × 12
∴ 3 JM = 60
- Divide both sides by 3
∴ JM = 20 units
