4 over 15 because when you multiply 8 times 7 and 21 times 10, you get 58 over 210. then you can divide it by 7 to get 8 over 30. Then I divided it by 2 to get 4 over 15.<span />

One exterior angle of a regular pentagon has a measure of (2x)”. What is the value of x?
USPshnik [31]

Answer:

x = 36°

Step-by-step explanation:

The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:

5 * 2x = 360

10x = 360

x = 36°

To which subsets of real numbers does the following number belong? square root of 30
LenaWriter [7]

In order to determine which subset it belongs, we must rewrite

\sqrt(30)

as

\sqrt(30)=\sqrt(2\times \times 3 \times 5)


\Rightarrow \sqrt(30)=\sqrt(2 \times 3\times 5)

\Rightarrow \sqrt(30)=\sqrt(2) \times \sqrt(3) \times \sqrt(5)


All these three numbers are irrational numbers, hence their product is also irrational


<h2>\Rightarrow \sqrt(30)</h2><h2>belongs to the set of irrational numbers</h2>
