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}

The length of a rectangle is 2 in longer than its width. if the perimeter of the rectangle is 44 in , find its area.
valkas [14]
P = 2(L + W)
P = 44
L = W + 2

44 = 2(W + 2 + W)
44 = 2(2W + 2)
44 = 4W + 4
44 - 4 = 4W
40 = 4W
40/4 = W
10 = W

L = W + 2
L = 10 + 2
L = 12

A = L * W
L = 12
W = 10

A = 12 * 10
A = 120 square inches <===
