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 $\bf{= \sqrt{6}}$

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

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

$\bf{\implies x^2 = 18}$

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

An angle in standard position measures 5п 8 radians. In which quadrant does the terminal side of this angle lie? O Quadrant I II

user100 [1]

Answer:

I've attached a picture of a unit circle with the quadrant labeled.

Calculate the degree of 5п 8 radians:

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

Locate the general location of 112.5° on the unit circle:

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

Find the quadrant it lies in:

Quadrant II

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!
