Answer:
Cos θ = √7/3
Step-by-step explanation:
From the question given above, the following data were obtained:
Sine θ = √2 / 3
Cos θ =?
Recall
Sine θ = Opposite / Hypothenus
Sine θ = √2 / 3
Thus,
Opposite = √2
Hypothenus = 3
Next, we shall determine the Adjacent. This can be obtained as follow:
Opposite = √2
Hypothenus = 3
Adjacent =?
Hypo² = Adj² + Opp²
3² = Adj² + (√2)²
9 = Adj² + 2
Collect like terms
9 – 2 = Adj²
7 = Adj²
Take the square root of both side
Adjacent = √7
Finally, we shall determine the value Cos θ. This can be obtained as follow:
Adjacent = √7
Hypothenus = 3
Cos θ =?
Cos θ = Adjacent / Hypothenus
Cos θ = √7/3

As i got.
60.8 is 64% of 95.
Step-by-step explanation:
Given number is;
95
We have to find at what percent, the value is 60.8
Let x be the percent.
Therefore;
x% of 95 = 60.8

Dividing both sides by 0.95

60.8 is 64% of 95.

Do you think the answer is C.147?
Im pretty sure you just multiply 12 by 108, in that case there would be 2160 rows
