OpenStudy (f_jayyy):

wouldnt it be 40?

OpenStudy (gabebae):

explain?

OpenStudy (mathstudent55):

You have two different 30-60-90 triangles. Find AC and BC using the triangles. The answer is AC - BC

OpenStudy (dr0zier99):

i think that the answer is b AC: \(\normalsize\tan(60) = \frac{AC}{10 \sqrt{3}} \implies \sqrt{3} = \frac{AC}{10 \sqrt{3}}\) \(\normalsize\ AC = 10 \sqrt{3} \times \sqrt{3} = 30\) BC: \(\normalsize\ tan(30) = \frac{BC}{10 \sqrt{3}} \implies \frac{1}{\sqrt{3}} = \frac{BC}{10 \sqrt{3}} \implies BC = 10\) \(\ AB = 30 - 10 = 20\)

OpenStudy (dr0zier99):

is that write

OpenStudy (mathstudent55):

|dw:1450106047582:dw|

OpenStudy (gabebae):

wow.. i'm so confused right now

OpenStudy (dr0zier99):

i say that the answer is b

OpenStudy (mathstudent55):

In a 30-60-90 triangle, the long leg is \(\sqrt 3\) times longer than the short leg.

OpenStudy (gabebae):

so 20 feet?

OpenStudy (dr0zier99):

i would think so

OpenStudy (anonymous):

me also
