Which angles are coterminal with −6π5 ? Select each correct answer. 14π/5 −16π/5 −π/5 −11π/5
wariber [46]
ANSWER

-  \frac{16 \pi}{5}  \: and \:   \frac{14\pi}{5}


EXPLANATION

Coterminal angles are angles in standard position that have the same terminal side.


To find an angle in standard position that is coterminal with

-  \frac{6 \pi}{5}

We add or subtract multiples of
2 \pi

The first addition gives,

-  \frac{6 \pi}{5}  + 2 \pi =  \frac{4 \pi}{5}


We add the second multiple to get,

-  \frac{6 \pi}{5}  +2( 2 \pi )=  \frac{14 \pi}{5}

Since this is the maximum value among the options, we end the addition here.


Let us now subtract the first multiple to get,


-  \frac{6 \pi}{5}  -   2 \pi =   - \frac{16 \pi}{5}


We end the subtraction here because this is the least value among the options.


Therefore the angles that are coterminal with
-  \frac{6 \pi}{5}
are

-  \frac{16 \pi}{5}  \: and \:   \frac{14\pi}{5}

Find range<br>of<br>f(x) =<br><img src="https://tex.z-dn.net/?f=1%20%5Cdiv%20%28%20%7Cx%7C%20%20-%20x%29" id="TexFormula1" title
SCORPION-xisa [38]

Step-by-step explanation:

We need to find thr range if

\frac{1}{ (|x|  - x)}

The absoulte value of something is positive.

So

\frac{1}{x - x}  =  \frac{1}{0}

This function isn't possible so no range exist.

What is X? I don't understand at all.
natima [27]
Angle A + Angle B = 180 degrees
180 = (6x -48) + (4x +38)
180 = 10x -10
190 = 10x
x = 19
Angle A = 6x - 48
Angle A = 6 * 19 - 48
Angle A = 115 -48
Angle A = 67 degrees

Angle B = 4x + 38
Angle B = 4*19 + 38
Angle B = 76 + 38
Angle B = 114
