Notice the picture,
recall your SOH, CAH, TOA
you have,
opposite side, 165
adjacent side, 50
and the angle
that means, we'll need Mrs. tangent
thus
![\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(\theta)=\cfrac{165}{50} \\ \quad \\ tan^{-1}\left[ tan(\theta) \right]=tan^{-1}\left[ \cfrac{165}{50} \right] \\ \quad \\ \theta=tan^{-1}\left[ \cfrac{165}{50}\right] \\ \uparrow \\ \textit{angle of elevation}\iff\textit{angle of depression}](https://tex.z-dn.net/?f=%5Cbf%20tan%28%5Ctheta%29%3D%5Ccfrac%7Bopposite%7D%7Badjacent%7D%5Cimplies%20tan%28%5Ctheta%29%3D%5Ccfrac%7B165%7D%7B50%7D%0A%5C%5C%20%5Cquad%20%5C%5C%0A%20tan%5E%7B-1%7D%5Cleft%5B%20tan%28%5Ctheta%29%20%5Cright%5D%3Dtan%5E%7B-1%7D%5Cleft%5B%20%5Ccfrac%7B165%7D%7B50%7D%20%5Cright%5D%0A%5C%5C%20%5Cquad%20%5C%5C%0A%5Ctheta%3Dtan%5E%7B-1%7D%5Cleft%5B%20%5Ccfrac%7B165%7D%7B50%7D%5Cright%5D%0A%5C%5C%20%5Cuparrow%20%20%5C%5C%0A%20%5Ctextit%7Bangle%20of%20elevation%7D%5Ciff%5Ctextit%7Bangle%20of%20depression%7D)
Answer:
The correct answer is Pete saves $2.10 by buying bulbs in packages of 3 for $6.39 each.
Step-by-step explanation:
Pete can buy daffodil bulbs in packages of 3 for $6.39 or in packages of 2 for $4.40.
He needs to buy 30 bulbs at a better price.
Money spent by buying bulbs in packs of 3 = 10 × 6.39 = $63.90.
Money spent by buying bulbs in packs of 2 = 15 × 4.40 = $66.
Money saved if bought in packs of 3 = 66 - 63.90 = $ 2.10.
Thus Pete should buy 30 daffodil bulbs in packages of 3 and save $2.10.

hope that helps!
95%=$79.50
100%= 79.50/95 X 100 = $83.68
Answer:
Equation: (x+9)² + (y+2)² = 100
4 points: (1, -2) (-1, 4), (-3, -10) (-19, -2)
(-3, 6) is on the circle
Step-by-step explanation:
(h, k) (-9, -2)
Equation: (x+9)² + (y+2)² = 100
4 points: (1, -2) (-1, 4), (-3, -10) (-19, -2)
(-3, 6) is on the circle
check: (-3 + 9)² + (6 + 2)² = 36 + 64 = 100 = 10²
