Question

Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.

Answer 1

A. \[\frac{ 1 }{ 2 }\] B. \[16\sqrt{3}\] C. 2 D. \[8\sqrt{3} \]

Answer 2

You can use the definition of sine to find x.

You can also use Pythagoras theorem: a^2 = b^2 + c^2 to find a.

Answer 3

to find x.

Answer 4

ratios of a 30 - 60 - 90 right triangle are
\[1:\sqrt3:2\]

Answer 5

I did pythagorean theorem and got

320=x^2

I dont know which answer choice = \[\sqrt{320}\] ....

Answer 6

you added the two squares. you should subtract.
16^2 = 8^2 + x^2
x^2 = 16^2 - 8^2

Answer 7

So...its \[\sqrt{192}\] and that is equivalent to 8 \[\sqrt{3} \]. is the answer D?
