The square of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two sides.
You can use Pythagoras' Theorem to calculate QR:
a^2 + b^2 = c^2
5^2 + 12^2 = QR^2
25 + 144 = QR^2
169 = QR^2
This means that the square root of 169cm is QR, which is 13cm.
SR is equal to QR, which means that SR is 13cm.

Step-by-step explanation:
Answer:
1) $101,400
2) $27,000
Step-by-step explanation:
1) For this, we can first find how much she makes in a year from her salary alone:
$2,200×12= $26400.
Now, she also received a commission of 2.5%, so we can take this percentage from 3 million to find the total from commission:
3,000,000×0.025= $75,000
Adding these two gives us a total of $101400.
2) We can use the Simple Interest Formula to solve this (I= Prt). Plug in the values given to give us:
I= 5000(1.08)(5)
I= $27000
