Question

Someone answer this Please

Answer 1

Answer:

15 miles

Step-by-step explanation:

The Pythagorean theorem states that $a^2+b^2=c^2$ where a and b are the two legs (the sides of the triangle that are adjacent to the right angle) and c is the hypotenuse (the longest side). This only applies to right triangles.

Plug 12 mi and 9 mi into $a^2+b^2=c^2$ as a and b.

$a^2+b^2=c^2\\12^2+9^2=c^2\\144+81=c^2\\225=c^2$

Take the square root of both sides

$15=c$

Therefore, the length of the hypotenuse is 15 miles.

I hope this helps!

Answer 2

The given triangle is a Right angled triangle,

So, by applying Pythagoras theorem :

${c}^{2} = {12}^{2} + 9 {}^{2}$

=》

${c}^{2} = 144 + 81$

=》

${c}^{2} = 225$

=》

${c} = \sqrt{225}$

=》

$c = 15$

hence, value of c = 15 mi
