I'm assuming that you want to know what we get when we multiply 15 by 3.
15 \times 3 = 45.

If you are confused, then read on. :)

The \times symbol means you add 15 exactly 3 times. 15+15+15=45.

Let's take 3 \times 2 for example. 3 \times 2 is when you add 3 for a total of 2 times. 3 + 3 = 6. You can also say that 3 \times 2 is when you add 2 for a total of 3 times. 2 + 2 + 2 = 6.

So 15 \times 3 = 45.
15 + 15 + 15 = 45
and
3 + 3 + 3 + 3 + 3 + 3 + 3  + 3 + 3 + 3 + 3 + 3 + 3 +3 +3 = 45.

So the answer is 45. :)

Using trig how do you answer this
Aneli [31]

Answer:

62.73° or 1.09 radians

Step-by-step explanation:

SOH CAH TOA

sin = \frac{opposite}{hypotenuse}, so sin (?) = \frac{8}{9}

this means that ? = sin^{-1}(\frac{8}{9}) or ? = arcsin(\frac{8}{9}), depending on what calculator you have

plugging in sin^{-1}(\frac{8}{9}) or arcsin(\frac{8}{9}) into calculator will get you

62.73° or 1.09 radians

use the corresponding answer depending on if the question asks for degrees or radians
