P left triangle = (2x+8) + (2x+7) + 2x
combine like terms
P left =6x+15
P right triangle = 2x+ 2x+ (3x+7)
combine like terms
7x+7
since the perimeters of the triangles are equal, set them equal
6x+15 = 7x+7
subtract 6x from each side
15 =x+7
subtract 7 from each side
8 =x
AB = 2x+8 = 2*8 +8 = 16+8 = 24
BC =2x+7 = 2*8+7 = 16+7 = 23
CA = 2x =2*8 = 16
PQ = 2x = 16
QR = 2x = 16
PR = 3x+7 = 3*8+7 = 24+7 = 31

Step-by-step explanation:
The approximate learning percentage can be estimated by using a doubling method.
If we breakdown the repetitions into three consecutive parts, we have:
1 - 2
2 - 4
3 - 6
then
1 - 2 → 46P = 39
P =39/46
P = 0.8478
P = 84.8%
2 - 4 → 39P = 33
P = 33/39
P = 0.84615
P = 84.6%
3 - 6 → 35P = 30
P = 30/35
P = 0.8571
P = 85.7%
The average value of P = (84.8 + 84.6 + 85.7)/3 = 85.03%
85%
From the tables of Learning Curves coefficient
The values are likened against times derived from 85% table factors at T

b. Using your answer from part a, estimate the average completion time per repetition assuming a total of 30 repetitions are planned. (Round your answer to 3 decimal places.)
The average completion time = ![\mathtt{\dfrac{T_1 \times \ Total \ time\ factor}{n}}](https://tex.z-dn.net/?f=%5Cmathtt%7B%5Cdfrac%7BT_1%20%5Ctimes%20%5C%20Total%20%20%5C%20time%5C%20factor%7D%7Bn%7D%7D)
At the total time factor 30, from the learning curves table , n(30) = 17.091
Thus:
The average completion time = ![\mathtt{\dfrac{46 \times \ 17.091}{30}}](https://tex.z-dn.net/?f=%5Cmathtt%7B%5Cdfrac%7B46%20%5Ctimes%20%5C%2017.091%7D%7B30%7D%7D)
The average completion time = ![\mathtt{\dfrac{786.186}{30}}](https://tex.z-dn.net/?f=%5Cmathtt%7B%5Cdfrac%7B786.186%7D%7B30%7D%7D)
The average completion time = ![\mathtt{26.2062}](https://tex.z-dn.net/?f=%5Cmathtt%7B26.2062%7D)
