Answer:
Hypotenuse (c) = 48.47
Perimeter = 111. 47
Step-by-step explanation:
To find the missing leg, you would need to square the other legs : 18^2 + 45^2 = c^2, which would be 324 + 2025 = c^2. Add those together and you get 2349. You need to get rid of the square on c, so you would square root both sides : √(2349) = c. Then find the square root of that, which is approximately 48. 47. To find the perimeter, all you do is add the sides together: a + b + c . So it would be 18 + 45 + 48. 47 = P, which is approximately 111.47.
