Question

mkaay medal&fan again :p

Answer 1

You can use the Pythagorean theorem to solve, as you're given that angle ABC is a right angle.
\[a^2 + b^2 = c^2\]
Here, c represents the hypotenuse (the longest side of the right triangle) and a and b represent the smaller sides of the triangle. Plugging the given values into the equation, we get
\[a^2 + 5^2 = 7^2\]
Now you should be able to solve for a, which represents side AB.

Answer 2

I'm still kinda confused :p , would that make it a? (3.46 miles) @DisplayError

Answer 3

Nope. Try solving the equation that I wrote in the previous post for a.\[a^2 = 7^2 - 5^2 = 49 - 25\]
