## anonymous one year ago If sin(x) = 1/2, what is cos(x) and tan(x)? Explain your steps in complete sentences.

1. anonymous

first of all you need to find angles such that sin(x)=1/2

2. anonymous

How do I do that exactly? Sorry I am just terrible at math :/

3. anonymous

there are two such angles: |dw:1444416994811:dw| the first one is well-known - x=30 degrees the another is easy to find - 180deg - 30deg = 150 deg

4. anonymous

in both cases cos(x) and tan(x) are different. when x=30: $\cos(x)=\sqrt3/2$ $\tan(x)=\sqrt3/3$

5. anonymous

when x=150 deg $\cos(x)=-\sqrt3/2$ $\tan(x)=-\sqrt3/3$
