No long explanations yet please. Just tell me Sin, Cos, or Tan first.

anonymous · Answer

to figure the height of the triangle

anonymous · Answer

tan65  needs to be utilized

anonymous · Answer

tell me the ratio according to the triangle...

anonymous · Answer

Thats what I thought. If i calculate the rest of the problem can you just tell me if i'm correct?

anonymous · Answer

sure...

anonymous · Answer

145 tan 65deg right?

anonymous · Answer

145 / tan 65deg

anonymous · Answer

Okay, now how did you figure it was Tan instead of Sin and Cos? Did you assume it was Tan because the degree was bordering the adjacent and hypotenuse?

anonymous · Answer

the angle given involved the opposite side given (145) and the height (unknown, x)

so tan65 = 145/x...
solving this ratio for x you have:
x = 145/tan65

anonymous · Answer

the unknown height is the adjacent side to 65degrees..

anonymous · Answer

So lets say we didn;t know the width of the triangle, knew the height (as 145 lets say), and the 65deg angle was on the other-side of the triangle. How would we solve it then? I can draw it if you need me too.
