Answer:
Step-by-step explanation:
When working with 45-45-90 triangles the hypotenuse is the same as the other legs multiplied by root 2. Therefore if you need to find the legs and already have the hypotenuse, divide the hypotenuse by root 2.
10/ sqrt(2) = 7.1 is the rounded answer.
to double check your work just multiply 7.1 by the square root of 2 and you'll get <em>close</em> to 10. (because the answer is rounded and not exact.)
Well, 4/5 is equal to 0.80 and 3/8 is equal to 0.375 and if you take the two and subtract them, you should end up with 0.425 or approximately 4/10 or 1/2.
The answer is 11 feet 6 inches
We can rule out the negative length.
