The ratio would be 3:4, or however you write ratios.
Hope this helped! :)

The probability that a transmission will last less than 14 years is 5%
Step-by-step explanation:
Given
Mean = 16 years
SD = 1.2 years
We have to find the probability that a transmission will last less than 14 years
First of all we have to find the z-score of the value
Z-score is given by:
We will use the z-score table to find the probability of being less than 14
So,
From z-score table we get the value for -1.6666
P(z = -1.666) = 0.04846
Converting into percentage
= 0.04846* 100
= 4.846
Rounding off to nearest percentage
5%
Hence,
The probability that a transmission will last less than 14 years is 5%

We'd need to figure out the side of the bigger pentagon, which is going to be messy, but we can do it!
The area of a pentagon equation is messy, and we need to solve for the side given the area, which would be sqrt((4*area)/((5(5+2sqrt(5)))^(1/2)) or sqrt((4*8)/((5(5+2sqrt(5)))^(1/2)) . We get this from the pentagon equation, multiplying both sides by 4 dividing (5(5+2sqrt(5)))^(1/2)) from both sides, then square rooting that to get the side length
Plugging it in, we get 2 and some more, and we multiply that by 2 to get the bigger side length. Plugging that into the area equation, we get a=32 and 32-8=24
