Answer:
3
Step-by-step explanation:
The answer is D. All you have to do is add all of the angles for each choice you're given. It has to add up to exactly 180, because every triangle is 180 degrees.
A rate in which the numerator and the denominator are equal to a rate of one
Hey! We can’t see a picture of the problem.
1, 3, 5, 7, 9 ......
notice, there are consecutive odd integers, every other number
skip one, another, skip one, another and so on
so, from 1 to 3, is 1 + 2 =3
5 is 3 +2
7 is 5+2
and so on
let us pick an odd integer, hmmm say "a"
to find the next odd one, it'd be "a + 2" of course :)
we know their sum is 316
so

once you found "a", the next one is, well, "a + 2" :)
