This is a guess, so if it's not right, I completely apologize.
I suppose the answer is C) The 1st angle is a right angle; definition of _|_.
They are both equivalent to 1/2
Answer:
Cosine F = (40 / 41)
Step-by-step explanation:
Since it's a right angle triangle, we can use
SOHCAHTOA method.
Where CAH = cosine F = adjacent / hypotenus.
Opposite (FH) = 9
Adjacent (HG) = 40
Hypothenus(FG) = 41
Cosine F = adjacent / hypothenus
Cosine F = 40 / 41
Cosine F = 0.9756
F = cos⁻(0.9756)
F = 12.68°
See attached document for better illustration on the triangle.
Answer:
18
Step-by-step explanation:
Use a proportion
=
8*6=48
So if we multiply 3*6, we get how many liters it takes to serve 48 people
3*6=18
35+(18x)
35 is just advance while we have to pay 18 extra everyday
