A circle is 360°.

Add the known angle measures and subtract the total from 360°.

115+105+60 =280°

360 - 280 = 80°

X= 80°

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}

Im trying to find the measure of the numbered angle:)??
bazaltina [42]
3 and 2 would be 122 since 3 and the 58° are a linear pair making them add up to 180. And 3 and 2 are vertical so they would be congruent.
4 would then have to be 38 since the three angles would have to measure up to 180.
And the 1 would have to be 36 with the same reasoning as before.
