So the way to figure out the sides of a right triangle, is basically
A^2 + B^2 = C^2
Letter A is the only one that would work, because the first number squared (times itself), added to the second number squared, would equal the third number squared. This is a basic principle of the pythagorean theorem, which I can explain in more detail if you'd like. :)
Answer:
d
Step-by-step explanation:
7x3=21
18x3=54
The propriety is zero propriety. Because 0 times a number is 0
What we want to do first is isolate the variable. To do this we need to multiply each side by 5 to remove the fraction
5 * 5 = 5*

w
Simplify the right side
5 *

w = 1w
Now simplify the left side
5 * 5 = 25
Then we get...
25 = w
There's your answer!
