We know that, In a Right Angled Triangle :

✿ (Hypotenuse)² = (First Leg)² + (Second Leg)²

From the Diagram :

✿ Hypotenuse = x

✿ First Leg \bf{= 2\sqrt{3}}

✿ Second Leg \bf{= \sqrt{6}}

\bf{\implies x^2 = (2\sqrt{3})^2 + (\sqrt{6})^2}

\bf{\implies x^2 = 12 + 6}

\bf{\implies x^2 = 18}

\bf{\implies x = 3\sqrt{2}}

user100 [1]

Answer:

<em>I've attached a picture of a unit circle with the quadrant labeled. </em>

<u>Calculate the degree of 5п 8 radians:</u>

\frac{5\pi }{8} =\frac{5*180}{8} =\frac{900}{8} =112.5

<u>Locate the general location of 112.5° on the unit circle:</u>

It's between 120°(\frac{2\pi }{3}) and 90°(\frac{\pi }{2}).

<u>Find the quadrant it lies in:</u>

Quadrant II

This is a tough one. Thanks to everyone who helps
VladimirAG [237]

Step-by-step explanation:

Hello there!

A good first step is to fill the t=blanks with 2 and 4.

Then proceed as follows:

3 |2x+4|=24\\3(2x+4)=24\\2x+4=\frac{24}{3} \\2x+4=8\\2x=8-4\\2x=4\\x=2

And there you are! Feel free to comment with questions, and have a grwat day!
