You would use the distributive property with the negative. So the second x becomes negative, but since the 7 is already negative it becomes positive. Think of it as if you put the two dashes together you can make a plus sign.

What is the length of the hypotenuse of the triangle below?

Vedmedyk [2.9K]

Answer:

Step-by-step explanation:

So here we have a 45-45-90 triangle.

This a special right triangle were the sides across from the 45 degree angles can be considered x, while the hypotenuse is two square roots of x.

Here since we have the sides across from the 45 degree angle we can conclude that $x = 9\sqrt{2}$

So if we wanted the hypotenuse we would just plug in this value of x like so:

$hyp = x\sqrt{2} \\$

$hyp = (9\sqrt{2})(\sqrt{2})$

$hyp = 9(2)\\$

$hyp = 18$

Therefore the hypotenuse is 18.
