Answer:
For right angle triangle,
we use Pythagoras theorem that is:
![c^{2} =a^{2} +b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3Da%5E%7B2%7D%20%2Bb%5E%7B2%7D)
c = ![\sqrt{a^{2} +b^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%7D)
For question 1:
c = ?
a = 40
b = 9
putting them in formula,
c = ![\sqrt{40^{2} + 9^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B40%5E%7B2%7D%20%2B%209%5E%7B2%7D%20%7D)
c = 41
For question 2:
c = ?
a = 12
b = 13
putting them in formula,
c = ![\sqrt{12^{2} + 13^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B12%5E%7B2%7D%20%2B%2013%5E%7B2%7D%20%7D)
c = approximately 17.69181
For question 3:
c = 35
a = 20
b = ?
putting them in formula,
![c^{2} =a^{2} +b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3Da%5E%7B2%7D%20%2Bb%5E%7B2%7D)
![35^{2} = 20^{2} + b^{2}](https://tex.z-dn.net/?f=35%5E%7B2%7D%20%3D%2020%5E%7B2%7D%20%2B%20b%5E%7B2%7D)
1225 = 400 + ![b^{2}](https://tex.z-dn.net/?f=b%5E%7B2%7D)
= 1225 - 400
= 825
![\sqrt{b^{2} } = \sqrt{825}](https://tex.z-dn.net/?f=%5Csqrt%7Bb%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B825%7D)
b = 5 ![\sqrt{33}](https://tex.z-dn.net/?f=%5Csqrt%7B33%7D)
For question 4:
c = 37
a = 20
b = ?
putting them in formula,
![c^{2} =a^{2} +b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3Da%5E%7B2%7D%20%2Bb%5E%7B2%7D)
![37^{2} = 20^{2} + b^{2}](https://tex.z-dn.net/?f=37%5E%7B2%7D%20%3D%2020%5E%7B2%7D%20%2B%20b%5E%7B2%7D)
1369 = 400 + ![b^{2}](https://tex.z-dn.net/?f=b%5E%7B2%7D)
= 1369 - 400
= 969
Taking square root on both sides
b = 31.12
Hope it helps.

Answer:
D
Step-by-step explanation:
All we need to know is that there are 2 PASTRIES, this makes it to where we can exclude any equation multiplying against two tea cups. Thus making D the only answer correct.
Answer:
48
Step-by-step explanation:
The mean of a number is the sum of all the numbers divided by how many numbers there are. We can set up this formula:
.
When we plug our values into this equation, we get:
. Solving this equation gets us sum = 6 * 8 = 48
