Answer:
A) 18°
Step-by-step explanation:
To find the measure of the indicated angle, we can use trigonometric ratios.
Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:
From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:
Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:
And we get:
? ≈ 18.4349488° ≈ 18°
So the answer would be 18°, or A.
I hope you find my answer to be helpful. Happy studying.
The monomial is a perfect cube is 
.
<h3>Perfect cubes;</h3>
Perfect cubes are the numbers that are the triple product of the same number.
We have to determine
Which monomial is a perfect cube?
A perfect cube monomial must have three identical roots, such that the product of the roots equals the perfect square monomial.
It must be possible for the coefficient of a perfect cube monomial to be written in the form n3, where n equals the cube root of the coefficient.
A perfect cube monomial must have exponents on the variables.
Then
The monomial is a perfect cube is;
![\rm= 343p^6q^{21}r^6\\\\= \sqrt[3]{ 343 }= 7](https://tex.z-dn.net/?f=%5Crm%3D%20343p%5E6q%5E%7B21%7Dr%5E6%5C%5C%5C%5C%3D%20%5Csqrt%5B3%5D%7B%20%20343%20%7D%3D%207)
Hence, the monomial is a perfect cube is .

Answer: 33.3%
Step-by-step explanation:
Since there are two sides to a coin, the probability is 1/2. Since there are 3 sections on the spinner, the probability would be 2/3. Since "and" means multiply in this scenario, your answer would be 2/6, which simplifies to 1/3, which, in percentage form to the nearest percent, is 33.3%.
