Based on the figure, which equation is true? Pic in comments thanks for all the help

OpenStudy (anonymous):

other than a direct answer. all i can tell you is find the 2 angles. using your ratios then find which are equal

OpenStudy (anonymous):

Which ratios do I use?

OpenStudy (anonymous):

well. think about what side you have on the top triangle. you have the adjacent and the hypotenuse

OpenStudy (anonymous):

remember the hyp is always opposite the right angle.

OpenStudy (anonymous):

I know that. So I'm using tangent

OpenStudy (anonymous):

for the top or bottom one?

OpenStudy (anonymous):

I have no idea. On the top we know the hypotenuse and adjacent which is cos. And on the bottom we know opposite and adjacent which is tangent. SO the bottom is tangent

OpenStudy (anonymous):

yep you got it. now have you solved for theta?

OpenStudy (anonymous):

What's theta....?

OpenStudy (anonymous):

Is there any way to get to the answer faster cause I really need to finish this class ':D

OpenStudy (anonymous):

or x and y. im just calling the angles theta sorry

OpenStudy (anonymous):

solve for the 2 angles then multiply 2cos(x)=? then tan(y)=

OpenStudy (anonymous):

you know the bottom is 45 45 90 and top is 30 60 90 by properties

OpenStudy (anonymous):

Ooooooooooookay...

OpenStudy (anonymous):

what did you get?

OpenStudy (anonymous):

Nothing I haven't done it cause Idk what to plug in where. Sorry I'm a visual person
