Set up a proportion. take 3/6 = 20/x
Cross multiply 3 * x = 6 * 20
Simplify 3x = 120
Divide by 3 x = 40
So the denominator of the bottom fraction is 40
By the Pythagorean Theorem:
h^2=x^2+y^2
Which just means that the hypotenuse (longest side) squared is equal to the sum of the side lengths squared...in this case:
h^2=5^2+13^2
h^2=25+169
h^2=194
h=√194
h≈13.93 in (to nearest hundredth of an inch)
Mckensey is correct as shown above.
Cara's mistake was in letting c be a side length instead of the length of the hypotenuse...
Answer:
c = 10
