HELP ME WITH THIS PLEASE

The answer is 5

hope it helps

n = 5 units

Step-by-step explanation:

We can solve this using 2 different equations which lead to the same

Equation #1: Sin(30) = n/10

=>Sin(30) * 10 = n

=> 5 = n

Equation #2: Cos(60) = n/10

=> Cos(60) * 10 = n

=> 5 = n

If a number is a whole number, it is in it's simplest radical form, therefore;    n = 5 units is the correct answer

Hope this helps!
