We are given a right triangle and we are asked to determine the hypotenuse given the measure of its sides. To do that we will use the Pythagorean theorem:

Now, we solve the square:

Now, we add the values:

Now, we take the square root to both sides:
![h=\sqrt[]{500km^2}](https://tex.z-dn.net/?f=h%3D%5Csqrt%5B%5D%7B500km%5E2%7D)
Solving the operations:

Therefore, the length of the hypotenuse is 22.361 kilometers.
Answer:
It is because you have to get rid of the power of 2 from c. In order to get rid, you have to square root it on both sides :
c² = 74
√(c²) = √74
c^(1/2×2) = √74
c = √74
Using Indices formula, (a^m)^n = a^(mn)
Answer:
D. 50
Step-by-step explanation:
7*30 - (54+29+22+28+12+15)
=210 - 160
=50
