Answer:

Step-by-step explanation:

we can use the trigonometric function in a right triangle

cos x = adjacent side to the angle /hypothenuse

cos 36°= x/10  ; multiply both sides by 10

10 * cos 36° = x ; make sure your calculator mode is in degrees

I just need help. So, with this, since it’s 6.633 then would it just go back to 6.63 or to 6.60?
Brums [2.3K]
When you round, if the number you are rounding is more than 0, it will never be rounded down to 0. So 6.63 can never be rounded to 6.60 since 3 is more than 0.
In order to round the hundredths, you need to look at the thousandths. 
The thousandths in 6.633 is the second 3.
Since 3 is less than 5, the first 3 will remain the same.
The correct answer is 6.63

hope this helps =)

5th root(8x^3/y^4)*5th root(4x^4/y^2)
kondaur [170]
Both are to the 5th square root, so you can multiply what is inside:
that is \sqrt[5]{ \frac{2^{5} x^{7} }{ y^{6} } }
=\frac{2x}{y} \sqrt[5]{\frac{ x^{2} }{y} }
