Help please! I’m stuck on this one and idk what to do first!

10 miles

Step-by-step explanation:

This is a right triangle. This is know because of the little square in the corner that indicates a right angle. Therefore, the Pythagorean Theorem can be used.

a^2+b^2=c^2

where a and b are the legs and c is the hypotenuse.

In this triangle, 24 and x are the legs, because they form the right angle. 26 is the hypotenuse because it is opposite the right angle.

x^2+24^2=26^2

Evaluate the exponents

x^2+576=676

Now, solve for x. First, move 576 to the other side of the equation by subtracting 576 from both sides.

x^2+576-576=676-576

x^2=100

Now, x is being squared. Take the square root of both sides.

√x^2=√100

x=√100

x=10

Use appropriate units

x=10 miles

The missing side length is 10 miles.

hi how are you doing today? if you ever need just tell me
