The equation used to find the missing lengths:
9 = __SR (5^2 + x^2)__
As long as it is a right triangle, this is called the Pythagorean Theorem

** FYI- if you wanted to SOLVE FOR THE MISSING SIDE X, then just switch around the original equation solving in terms of x:

Answer:
6
Step-by-step explanation:
We have y ∝ x which is another way of saying y varies directly with x
We can rewrite the direct proportion relation y ∝ x as y = k.x where k is a constant - the constant of proportionality
So y = kx or x = y/k
using y and x values know, we can solve for k and then solve for any x given y
We have
y = 37.4 = k (17)
Therefore k = (37.4/17) = 2.2
To find x given y = 13.2, use the second equation
x = y/k = 13.2 / 2.2 = 6
Answer:
One
Step-by-step explanation:
An equilateral triangle has equal side lengths.
With the given information, you can construct one equilateral triangle, with the sides measuring 7cm each.
The sides of the equilateral triangle can't be mixed up, they must stay the same.
Hope this helps.
The answer to your question is 18 thank me later!
6 out of 20=what percent?
6/20=x%
percent means parts out of 100
x%=x/100
6/20=x/100
time both sides by 100
30=x
answer is 30% passed
100-30=70
70% is answer
