You know how Soh Cah Toa applies to right triangles; you can assign the adjacent side = 4 and hypotenuse = 7
CosФ = (adjacent) / (hypotenuse)
Then with the Pythagorean theorem
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
b = √(33)
So "b" is the opposite side.
SinФ = (opposite) / (hypotenuse) = √(33)/7
TanФ = (opposite) / (adjacent) = √(33)/4
Answer:
5: Permutation. 6: Combination
Step-by-step explanation:
Being that the team of Basketball players are <u>Arranging</u> who will change the water cooler, then the Answer is <u>Permutation</u>.
Mei has homework, and she's deciding which subject to do first. She has a <u>Selection</u> of choices, thus being the Answer- <u>Combination</u>.

Answer:
1
Step-by-step explanation:
can be expressed as 
= 
Similarly 
can be expressed as 
= 
Numerator becomes:
· 
= 
Denominator becomes:
· 
=
Since numerator = Denominator,
Answer = 1
Edit reason: typo
Answer:
a or b
Step-by-step explanation:
4
You can just put this into a calculator:
1/2^2 = 0.25
3×5-3 = 12
1^3 = 1
0.25 × 12 + 1 = 4
