X = 4
Use division divide both sides by 3
3x/3 leaves x
12/3=4

x=4
Answer:
25 cm.
Step-by-step explanation:
If the hypotenuse is x cm long the 2 legs are x-5 and x-10 cm long.
So by the Pythagoras theorem:
x^2 = (x - 5)^2 + (x - 10)^2
x^2 = x^2 - 10x + 25 + x^2 - 20x + 100
x^2 - 30x + 125 = 0
(x - 5)(x - 25) = 0
x = 5, 25
We can discard x = 5 because that would make the lengths of the legs negative so the hypotenuse = 25 cm long.
The answer should be 299/52=almost 6 hours.
This means that every 1 inch in the drawing is 24 inches of the actual size.
Hope this helps!
