C because the first one she picks is 1/6 chance and since she took one there's five left so the second marble is 1/5 and when you multiply 1/5 and 1/6 it is 1/30
The answer is 15
To find the answer set up an equation like this
a2 + b2 = c2 (2 means squared)
Here we are trying to find the value of a so we know the values of b and c.
a2 + 20(squared) = 25(squared)
20 squared equals 400
25 squared equals 625
a2 + 400 = 625
Subtract 400 from 625 which equals 225.
Now we find the square root or closest square root of 225.
The square root of 225 is 15. 15 x 15 = 225

Answer:
Step-by-step explanation:
Cindy is correcy because on "Step 1:" the multiplication was correctly distributed over the subtraction in paranthesis 5(x-2) = 5*x- 5*2 = 5x-10.
Henry was wrrong because he distributed 5 only over x and not over -2 as well 5(x-2) ≠ 5*x-2
Take the inverse cosine of 0.5162
x=59 degree
