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.
Answer:
x = 55
Step-by-step explanation:
The "equals" sign means both sides are equal. You want to isolate the x. So subtract 22 from both sides.
62+15-22 = x
62-22 = 40; 40 + 15 = 55
x = 55
