Answer:
height for the building = 551.8 ft
Step-by-step explanation:
The info given describes the shape of a right triangle.
Thus:
Reference angle = Angle of elevation = 23°
Opposite side = height of the building = ?
Adjacent side = 1,300 ft
Apply trigonometric function, TOA:
Tan 23 = Opp/Adj
Tan 23 = Opp/1,300
1,300 × Tan 23 = Opp
551.817261 = Opp
Opp ≈ 551.8 ft
height for the building = 551.8 ft
Answer:
![2\frac{1}{2}\ liters](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D%5C%20liters)
Step-by-step explanation:
step 1
Convert mixed number to an improper fraction
![1\frac{1}{5}=\frac{1*5+1}{5}=\frac{6}{5}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B1%2A5%2B1%7D%7B5%7D%3D%5Cfrac%7B6%7D%7B5%7D)
step 2
Using proportion
![\frac{3}{(6/5)}\frac{liters}{doors} =\frac{x}{1}\frac{liters}{door}\\ \\x=3/(6/5)\\ \\x=15/6\ liters](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B%286%2F5%29%7D%5Cfrac%7Bliters%7D%7Bdoors%7D%20%3D%5Cfrac%7Bx%7D%7B1%7D%5Cfrac%7Bliters%7D%7Bdoor%7D%5C%5C%20%5C%5Cx%3D3%2F%286%2F5%29%5C%5C%20%5C%5Cx%3D15%2F6%5C%20liters)
step 3
Convert to mixed number
![\frac{15}{6}\ liters=\frac{12}{6}+\frac{3}{6}=2\frac{1}{2}\ liters](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B6%7D%5C%20liters%3D%5Cfrac%7B12%7D%7B6%7D%2B%5Cfrac%7B3%7D%7B6%7D%3D2%5Cfrac%7B1%7D%7B2%7D%5C%20liters)
Answer:
B) 4
Step-by-step explanation:
Tan is opposite/adjacent. That means that 3 is the opposite side while 4 is the adjacent side.
What is the question? If you are only trying to expand the
expression then the answer would be:
1/4 (5y-3)+ 1/16 (12y+17)
(5y/4) – (3/4) + (12y/16) + (17/16)
1.25y – 0.75 + 0.75y + 1.0625
2y + 0.3125
If you are trying to find for y, then you forgot to equate
it to 0, that is:
2y + 0.3125 = 0
2y = -0.3125
<span>y = 0.15625</span>
Answer:
C
Step-by-step explanation:
because you have to foil then do -b/2a
