Ineed my work shown so give some sort of brief explanation! a right triangle has legs measuring 18 in and 45 cm. find the missing side, what would the perimeter be in cm?

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.

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
