Rewrite the decimal as the front as a fraction in simplest form 0.27

2 answers:

27/100, I think this is what you meant but the "as the front" part of the question puzzled me a little bit. If you meant basically make 0.27 into a fraction in simplest form, this is the answer.

So .27 means .27/1 or 2.7/10 or 27/100 or 270/1000 and so on

Calculate interior angle of a regular 15 sided polygon

AleksAgata [21]

Answer:

156°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 15 , then

sum = 180° × 13 = 2340°

interior angle = $\frac{sum}{n}$ = $\frac{2340}{15}$ = 156°

Select the correct answer from the drop down menu. with references to the figure, sin x =

Lubov Fominskaja [6]

Answer:

.894

Step-by-step explanation:

First thing to do is to solve for the height of the triangle, BD. That's easy. We have the length of the hypotenuse and the base, so Pythagorean's Theorem gives us that the height is 8.003255588 which rounds nicely to 8. Now you have to call on the fond memories you have of the geometric mean in right triangles to solve the rest. For the sin of x you need the hypotenuse of that smaller right triangle on the left, side AB. First let's use geometric mean to find AD. The formula for that, now that we know the height, is

$BD^2=(AD)(DC)$

Filling that in with numbers we have

$8^2=(AD)16$ and

64 = 16(AD). Solve for AD to get that AD has a length of 4. Now we know two of the three sides in that smaller triangle on the left and can solve for the hypotenuse.

$8^2+4^2=c^2$ and

$64+16=c^2$ so

c=√80 which simplifies to 4√5. That means that the sin ratio for x is

$\frac{8}{4\sqrt{5} }$

which divides out to .894
