Answer:
Option A,
Step-by-step explanation:
<u>Step 1: Determine the numbers that are multiples of 3</u>
8 → Not a multiple of 3
9 → Multiple of 3
14 → Not a multiple of 3
19 → Not a multiple of 3
25 → Not a multiple of 3
34 → Not a multiple of 3
38 → Not a multiple of 3
<u>Step 2: Determine the probability of chosing a multiple of 3</u>
Since we only have 1 number that is a multiple of 3 out of the 7 given numbers, that means that we do the following:
Answer: Option A,
since the hypotenuse is just the radius unit, is never negative, so the - in front of 8/17 is likely the numerator's, or the adjacent's side
now, let us use the pythagorean theorem, to find the opposite side, or "b"
so... which is it then? +15 or -15? since the root gives us both, well
angle θ, we know is on the 3rd quadrant, on the 3rd quadrant, both, the adjacent(x) and the opposite(y) sides are negative, that means, -15 = b
so, now we know, a = -8, b = -15, and c = 17
let us plug those fellows in the double-angle identities then
