Answer:

Positive angles located in the fourth quadrant may be described as 270≤Ф≤360 .

The option is

4. 270≤Ф≤360

Step-by-step explanation:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

For Example.

Quadrant I - 0 to 90°

Quadrant II - 90° to 180°

Quadrant III - 180° to 270°

Quadrant IV - 270° to 360° ( 4. 270≤Ф≤360 )

Hence,Positive angles located in the fourth quadrant may be described as 270≤Ф≤360 .

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV - 0° to -90°

Quadrant III - - 90° to -180°

Quadrant II - -180° to -270°

Quadrant I - -270° to -360°

Simplify 4√16 + 8√16

Mumz [18]

$4\sqrt{16} + 8\sqrt{16}$ :

Since $\sqrt{1} =1$ , we get:

$4\cdot \:1\cdot \:6+8\cdot \:1\cdot \:6=24+48=72$

-----------------------------------------------------------------------------------

$7\sqrt{4} *3\sqrt{8}$

We have $\sqrt{4}=2$

simplify $\sqrt{8} = \sqrt{2^3} = \sqrt{2^2*2}$

then the radical rule is used: $\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}$

⇒ $\sqrt{2^2*2} = \sqrt{2^2} \sqrt{2}= \sqrt{4}\sqrt{2} =2\sqrt{2}$

Now we have $\sqrt{4}=2$ and $\sqrt{8}=2 \sqrt{2}$

$7\sqrt{4} *3\sqrt{8} = 7*2*3*2\sqrt{2} = 84 \sqrt{2}$

-----------------------------------------------------------------------------------

$2\sqrt{4}+5 \sqrt{9}$

$2\sqrt{4} =2*2= 4$ and $5\sqrt{9} =5*3= 15$

$2\sqrt{4}+5 \sqrt{9} = 4+15 = 19$

-----------------------------------------------------------------------------------

$4\sqrt{5} -2\sqrt{5} = 2\sqrt{5}$

since $2\sqrt{5}$ is the half of $4\sqrt{5}$

-----------------------------------------------------------------------------------

$-4\sqrt{2}\:+\:5\sqrt{2} =1 \sqrt{2} = \sqrt{2}\\$ (-4+5=1)

What is the measure of angle 5?

marishachu [46]

Answer:

∠ 5 = 133°

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent and supplementary, thus

∠ 1 = 180° - 47° = 133°

∠ 1 and ∠ 5 are corresponding and congruent, thus

∠ 5 = ∠ 1 = 133°
