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.
The half of a cake has volume which can be divided by 3
-5x
The basic formula for slope of a line is
y = mx + b
where m is the coefficient of x and the slope.
Your equation is already in the right formula. The number there is -5x as your slope. Good luck!
10,000-1,000=9,000 -100
8,900,i think maybe
