Answer:
11.8
Step-by-step explanation:
So, we know the triangle is 25 feet. So, we are gonna put the ? as X. So, it is solve for X. We would want to subtract these numbers to get the answer
25 - 8 = 17
Then we would subtract again, but we would want to subtract with the answer we got. So, we would subtract with 17.
17 - 5.2 = 11.8
We can't subtract anymore.
So, X= 11.8
