#1
$sin(51^o)= \frac{y}{12} \ \ \to \ \ y=12*sin(51^o)=12* 0.7771 \approx 9.33$

#2
$\theta=arccos( \frac{5^2+13^2-12^2}{2*5*13}) = arccos( \frac{25+169-144}{130})=arccos( \frac{50 }{130})= \\ \\ arccos(0.3846) \approx67.4^o$

#3
$tan(13^o)= \frac{x}{24} \ \ \to \ \ x=24*tan(13^o)=24* 0.2309 \approx 5.54$

#4
$sin(20^o)= \frac{10}{x} \ \ \to \ \ x= \frac{10}{sin(20^o)} = \frac{10}{0.342} \approx 29.24$

dimulka [17.4K]

Answer:

Rational

Step-by-step explanation:

$\sqrt[3]{125}$ is also equivalent to 5

The definition of a <em>rational </em>number is any whole number, fraction, or decimal that ends or repeats, while an <em>irrational </em>number is any number that cannot be turned into a fraction.

5 is a whole number, and therefore, is a rational number.

How much carpet does Jordan need to cover the surface of the post including the bottom

Artist 52 [7]

Answer:

It would be 3,800

Step-by-step explanation:

You have to find the surface area of the post

( ( 90 x 10 ) x 4 ) + ( 10 x 10 ) x 2 ) = 3,800

3,600 + 200 = 3,800

Hope this helps
