Hey there
1 km = 1000 meters
So 5 km will equal 5000 meters
.1 will equal 100 meters
5.1 km = 5100 meters
<span>100,000 centimeters = 1 kilometer
</span>5.1 km = 510000 centimeters
Hope this helps
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.
Is this chemistry, their are many apps online that do you it automatically for u
