Question

A building lot in a city is shaped as a 30° -60° -90° triangle. The side opposite the 30° angle measures 41 feet.

a. Find the length of the side of the lot opposite the 60° angle.









b. Find the length of the hypotenuse of the triangular lot.









c. Find the sine, cosine, and tangent of the 30° angle in the lot. Write your answers as decimals rounded to four decimal places.

Answer 1

Anyone please help?

Answer 2

So this is basically what we have here, right?

Answer 3

i think so it does not give me a picture

Answer 4

tan30= x/41

Answer 5

okay so Tan stands for Tangent right? sorry im so bad at math

Answer 6

-6.40533119665 is what i got when i typed in tan30 so thats correct? I dont understand how you got 41

Answer 7

Right. If you type tan30 in a calc it comes up as about 0.58.
so 0.58=x/41,
try getting x by itself

Answer 8

x=23.78?

Answer 9

Bingo! So that's the answer to question A

Answer 10

excellent!!
okay now to b :)

Answer 11

According to SohCahToa, what's Cos90 =?

Answer 12

-0.44807361612

Answer 13

but the 90 degrees is negative does that make a diffrence?

Answer 14

Cosine is adjacent over hypotenuse so it would be cos90 = 23.78/y

Answer 15

Ohrlly? I don't know how to do negative angles D:

Answer 16

hmmm, i have no idea either but to do it the way you said i would have to get y by itself so i would multiply 23.78 by itself and then do the same to -90?

Answer 17

lol the negatives throw me off, let's try tagging someone else xD

Answer 18

okay =)

Answer 19

oh hello there!
