First way
arcsin(1/4) means that 1/4 sin of the angle.
sin(α)=1/4
sin²α+cos²α=1
(1/4)²+cos²α=1
cos²α=1-1/16 =15/16
cosα=+/-(√15)/4
<span>Second way
</span>
sin(α)=1/4 =opposite leg/hipotenuse
cos(α)=adjacent leg/hypothenuse
adjacent leg =√(hypotenuse²- Opposite²)=√(16-1)=√15
cosα=+/-√15/4
For one value of sinα, possible 2 values of cosα.
Answer:
The total number of games won by Unicorn is 40.
Step-by-step explanation:
- We are given with a word problem
- We are asked to find the number of unicorns played during the season
- We can do this in two steps
Step 1: Finding the win percentage
Step 2: Finding the number of unicorns played during the season
Step 1 of 2
Let the number of games played by unicorn be x.The unicorn won 60% of the first x-10 games That is 
Combining the 8 games we get,

Step 2 of 2
The unicorn totally won 65% of the games played.
That is 
Equating both the equation gives

Answer:184ft²
Step-by-step explanation:2(5×10)+2(4×6/2)+(6×10)
100+24+60=184

The Federal Insurance Contributions Act (FICA) is made up of
two items, Social Security and Medicare taxes. For 2016, the Social Security
tax rate is 6.2% on the first $118,500 wages paid. The Medicare tax rate is
1.45% on the first $200,000 and 2.35% above $200,000. Since the total earnings is
only $110,700 which is not yet taxable. So there is no taxable earnings yet.
