**Answer:**

cot (X) = 5/12

**Answer:**

3/8

**Step-by-step explanation:**

**Find the common factor, which is 24.** To make the other fractions have a denominator of 24, multiply the denominator and numerator by a factor that will have the denominator get 24 (the multiplied number has to be the same for the top and bottom). 27/24 divided by 3 is 27/24.**You will get 1/4=6/24, and 5/6=20/24. 6/24 + 20/24 = 26/24 + 1/24= 27/24. Divide by 3 since there are 3 numbers. Once you are done dividing, you will get 27/72, and 3/8 is the simplified answer.**
