One angle of a right triangle measures 60°. The side opposite this angle measures 15 inches.
Delicious77 [7]

Step-by-step explanation:

To solve this question I would use the sin rule.

The sin rule states that

\frac{a}{ \sin(a) }  =  \frac{b}{ \sin(b)  }

Therefore if you substitute in your numbers you get:

\frac{a}{ \sin(90) }  =  \frac{15}{ \sin(60) }

If you rearrange that you get:

a =  \frac{15}{ \sin(60) }  \times  \sin(90)

Therefore a = 17.3 Inches (to 3 sf)

This can also be done with basic trigonometry where you would get

\sin(60)  =  \frac{15}{h}

Rearranging to

h =  \frac{15}{ \sin(60) }

meaning the answer is 13.7 inches

Use the table definitions of H(t) and r(t) shown below to find (H o r)(3.0)
fredd [130]

Answer:

C

Step-by-step explanation:

Given the tables of H(t) an r(t), we want to find:

(H\circ r)(3.0)

As stated, this is equivalent to:

=H(r(3.0))

Using the r(t) table, we can determine that:

r(3.0)=2.0

Therefore:

H(r(3.0))=H(2.0)

And by using the H(t) table, we can determine that:

H(2.0)=2.5

So, our answer is C.

Over the next week you want to watch a movie a day. In how many ways can this be done if you have 8 movies
Leto [7]
<span>You can select from any of the 8 on the first day, leaving 7 to choose from on the second day, leaving 6 for the third. So, 8 x 7 x 6 x 5 x 4 x 3 x 2 or 8! That's 8factorial, so multiply those out or use a calculator to get 8! and that is your answer.</span>
