Help please abs thank you

Answer 1

Answer:

$4\sqrt{5}$ = 8.94

Step-by-step explanation:

To solve this problem, use the Pythagorean theorem;

$a^{2} + b^{2} = c^{2}$

Where "a" and "b" are the legs of the right triangle ( the sides that are adjacent to the right angle of a right triangle), and "c" is the hypotenuse, the side that is opposite the right angle.

In the problem, the measure of each leg is given;

$a = 4, \\b = 8$

Now all one has to do is substitute these values into the formula and solve;

$a^{2} + b^{2} = c^{2}\\4^{2} + 8^{2} = c^{2}\\16 + 64 = c^{2}\\80 = c^{2}\\\sqrt{80} = c\\4\sqrt{5} = c$
