Follow the a² + b² = c² formula
The hypotenuse always equal the c
a and b can be the other two numbers and are interchangeable
plug in 5 and 6 into a and b
(5)² + (6)² = c²
simplify
25 + 36 = c²
add
c² = 61
isolate the c, root both sides
c² = 61
√c²= √61
c = √61
Roots are Irrational numbers, and so D) irrational number should be your answer
hope this helps

Answer:
11
Step-by-step explanation:
<h2>You are technically using PEMDAS, since x equals 6 heres what you do. 2 x (6 + 1) -3</h2><h2>Perenthesies first: 6 + 1 =7 now you mulitiply</h2><h2>2 x 7 = 14 so then subtract 14 - 3= 11</h2><h2 />
You need to set this up with a proportion and solve. 18/x-5 = 13.5/12.
cross multiply 13.5x-67.5=216
now solve for x
13.5x=283.5
x=21
the missing side is equal to 21-5, which is equal to16
