the answer would be 19.2

Answer:

19.2 or 19.20

Step-by-step explanation:

  1. Side 25=hypotenuse because it is across from the rightness of the triangle
  2. This means that teh unknown side is a leg, as well as the side that says 16
  3. This makes our equation: a²+16²=25²
  4. Next we solve
  5. 16²=256 and 25² is 625 so now our equation is a²+256=625
  6. We then subtract 256 from both sides which leaves us with x²=369
  7. To find the value of x, we take the square root of both sides. This leaves us with X=19.2
