The answer to what the length of the leg would be is 15.
You would do this problem by first writing down your Pythagorean Theorem, which is a^2 + b^2 = c^2.
Since we have our hypotenuse which is c^2 in our equation, we would write or insert the number we have.
So our equation could be that a or b leg equals 20, it doesn’t matter which one.
So we could write, 20^2 + b^2 = 25^2. So we don’t know what b leg is.
First we should figure out what 20^2 is and what 25^2 is.
20^2 is 400 and 25^2 is 625.
Our equation now comes to 400 + b^2 = 625.
Now we take 400 and subtract it from
625 -> 400 + b^2 = 625
-400.
So 625 - 400 comes out to be 225.
Lastly instead of squaring or putting 225 to the second power, we do the opposite.
So instead of squaring 225 we must square root 225. √ 225 .
The square root of √ 225 comes out to be 15.

Answer:
a)The total amount of her weekly stock sales = $7,200
b) The total amount of her yearly stock sales = $350,000
Step-by-step explanation:
(a) Let us assume that the total a mount of her sales in a week = $m
Commission earned in a week = $288
Now, 4 % of her total sales = $288
or, 4% of ($m) = $288
⇒
or,
⇒ m = $7,200
Hence, the total amount of her weekly stock sales = $7,200
b) Let us assume that the total amount of her sales in a year = $k
The total amount of commission earned = $14,000
Now, 4 % of her total sales = $14,000
or, 4% of ($k) = $14,000
⇒
or,
⇒ k = $350,000
Hence, the total amount of her yearly stock sales = $350,000
