Answer:

Step-by-step explanation:

It's a 30-60-90 triangle. The sides of a 30-60-90 triangle are in the ratio 1:√3:2

The side opposite the 90° angle is 12√3, so the side opposite the 30° is (12√3)/2 = 6√3.

The side opposite the 60° angle is (6√3)√3 = 18

x = 18

y = 6√3

Evaluate the expression 2n - 6 if n = 16.
V125BC [204]

Answer:

26

Step-by-step explanation:

2n-6

Given that:

n=16

To evaluate the expression, we must simply substitute the given value of n, which is 16, for n:

2(16)-6

Multiply:

32-6

Subtract:

26

-

To check your work, simply set the given expression equal to our solution, 26:

2n-6=26

Add 6 to both sides of the equation:

2n=32

Divide both sides of the equation by the coefficient of n, which is 2:

n=16

Since it matches the given value of n, our solution is correct!
