sin x = cos 54 = sin (90-54) = sin 46
Hence x = 46 deg
Same technique. Sin 21 = cos (5x+9) = sin (90-5x-9)
81-5x = 21
Or 5x = 60
Or x = 12 deg
hope it helps
Answer:
nothing much u
Step-by-step explanation:
From the expression <span>8(x +4) (y +4) (z 2 + 4z + 7),
</span>the factors are 8, (x+4), (y+4), <span>(z^2 + 4z + 7) since each of these factors, when you divide that to the whole expression won't give a remainder</span>
Answer:
x = 2

Answer:
Bryden will get a total of $20 for this four quarters
Step-by-step explanation:
Here, we have a collector offering to buy state quarters for 2,000% of their face value.
Now, we have 4 state quarters with the value of 1 being 25 cents.
Since 1 has a value of 25 cents, then four will have a face value of 25 cents * 4 = 100 cents or better still $1
Now, the offer is 2000%
So the amount to be paid in dollars will be 2000% of $1.
Mathematically, that would be;
2000/100 * 1 = 2000/100 = $20
