Question

Pls help me with my homework

Answer 1

Answer:

b = 8

Step-by-step explanation:

Using Pythagorean Theorem, a$a^{2} +b^{2} =c^{2}$, we just plug in what we know.

We know that the hypotenuse, c, is 10 km. We also know that one of the other side lengths is 6 km, we can plug that into either a or b.

Now, our equation will be: $6^{2} +b^{2} =10^{2}$.

You could also use the equation: $b^{2} =10^{2} -6^{2}$.

Next, we'll just solve the equation.

$10^{2} =100$, $6^{2} = 36$

$b^{2} =100 - 36$

$b^{2} = 64$

$\sqrt{b^{2} } = \sqrt{64}$

b = 8

Good luck :D
