anonymous · Answer

what information do you have? you have, the adjacent side and  one angle

anonymous · Answer

You are asked to calculate the altitude (i.e. the opposite side)

anonymous · Answer

Well you know, tan = opposite side/adjacent side, right?

anonymous · Answer

yes

anonymous · Answer

so we would need to plug in the terms?

anonymous · Answer

Tan 30  = 0pposite/ 6.7

anonymous · Answer

Therefore, opposite = Tan 30 degrees x 6.7

anonymous · Answer

use your calculator: Tan 30 degrees =0 .5777

anonymous · Answer

i did but i got -6.40

anonymous · Answer

0.5777 x 6.7 = 3.86

anonymous · Answer

Enter this: tan, 3, 0, equals, what do you get?

anonymous · Answer

i used my other one and i got that answer! thank you so much!
