Geometry

A question for the smart guys. I am trying to solve for C. Can someone help me out?

[JeffG2]

Well, since all the smart guys seem to be busy today, let's give a D math student a crack at it....


C = 8.5?

Yep, C=8.464

oposite over adjacent = tan (angle B)

trig

That is what I got, but something isn't making sense. Tan(10) X 48 = 8.5. Maybe I am not explaining myself. I'll post more later. Thanks for the help.

What isnt making sense? The drawing doesnt, but the actual numbers work.

8.46369507400632 actually

haven't used tan for nearly 20 years but i still remember the maths brainwashing.

What isn't making sense is that in the drawing, the marked angle is not 10 degrees, it's closer to 30. So visually it looks like C should be much larger than 8.5... but the math is right.

Oh and as you pointed out in your reply subject, it's technically trigonometry, not geometry. (not trying to be a pedant, really, i'm not)

oh... I thought I had successfully forgotten all that Tan Cos Sine stuff... now you had to go and remind me of it all... damn you all!!!

math

My issue was I was using and on-line calculator. I ran to the store and bought a scientific calculator and things started to make sense

START MENU -> RUN -> CALC -> ENTER

VIEW MENU -> SCIENTIFIC
