Question

PLEASE HELP WILL FAN AND MEDAL. (See picture in the next comment for the problem)
a. 67 feet b. 72 feet c. 78 feet d. 27 feet

Answer 1

So I guess this has to do with trig?

This should be fun :)

Answer 2

So we know the angle and we have a side. What should we use? sin? cos? tan?

Answer 3

Ooh! And i gives you a table of the valuse so you don't need to calculate it yourself with a calculator :)

Answer 4

it gives*

Answer 5

oh okay

Answer 7

Uh. Im really sorry because I haven't been taught that yet, so could you guide me through it? Im really sorry :(

Answer 8

\[Sin ~\theta= \frac{ opposite~side }{hypotenuse }\]

\[Cos ~\theta = \frac{ adjacent~side }{ hypotenuse }\]

\[Tan ~\theta = \frac{ opposite~side }{ adjacent~side }\]

Answer 9

oh okay. so how do we solve for the opposite side?

Answer 10

\(\theta\) is the angle we have. Which in our case is 68 degrees.

Answer 11

ok

Answer 12

And waht is teh hypotenuse of our triangle? @tvinsant

Answer 13

what is the**

Answer 14

1. Look at the given information and the info you are looking for.
2. For the given angle, the two sides (given and unknown) are which sides? adj, opp, hyp?
3. Based on the answer to step 2, determine which trig function you need to use.
4. Use the correct trig function and plug in all known amounts.
5. Solve for the unknown.

Answer 15

oh the hypotenuse is 72

Answer 16

Correct.

Answer 17

Correct. hyp = 72
Next, what is the angle?

Answer 18

And so which trig function would we have to use? And that ^

Answer 19

68

Answer 20

Great. A = 68, or \(\theta = 68\)
You already know that opp = x (unknown)

Answer 21

What is the side we want to find? Is it the adjacent side or the opposite side to the angle 68 degres?

Answer 22

um would we use cos?

Answer 23

We need to relate the angle to the opp and hyp.

Answer 24

Look in my figure above where I wrote the formulas for sin, cos and tan.
Which formula has the hyp and the opp?

Answer 25

the sin A
