Question

Math help pls

Answer 1

@Hero

Answer 2

Use \(\tan(\theta) = \dfrac{\text{opp}}{\text{adj}}\) To set up your problem do the following:
1. Pick an angle. Let that be your \(\theta\).
2. Find the side opposite that angle. This value goes in the numerator of the fraction.
3. Find the side adjacent to the angle. This value will go in the denominator of the fraction. Then isolate \(x\) and simplify the expression for \(x\)

Answer 3

6/x?

Answer 4

If you're going to write it out, you should post BOTH sides of the equation. It matters what angle you have chosen.

Answer 5

I chose angle 67, the side opposite is 6, the side adjacent is x?

Answer 6

Yes, correct. You still have to properly isolate x though. You need to represent what you've written in equation form or post the expression you found for x. And after isolating x, make sure your calculator is set to degrees.

Answer 7

how do I find an expression for x?

Answer 8

Have you setup the equation yet? I can explain after you post the equation with the values you intend to use.

Answer 9

idk how to set up the equation, should I use the angles 67, 23?

This explains how to setup your equation.

Answer 11

how do I isolate x?

Answer 12

Multiply both sides by the denominator. Then cancel any factors of one. You won't post your equation setup so I'm limited in how I can help you.

Answer 13

wasn't my equation setup 6/x?

Answer 14

that expression is only one side of the equation. An equation has an equal sign between two expressions on either side of the equal sign.

Answer 15

or tan(67)=6/x?

Answer 16

Finally. To isolate \(x\), do the following:
1. Multiply both sides by \(x\). Then simplify.
2. Divide both sides by tan(67) then simplify.
3. Enter the expression for x into your calculator (make sure it is set to degrees).

Answer 17

14.1?

Answer 18

That's not what I got

Answer 19

Did you make sure your calc is set to DEGREES?

Answer 20

yep

Answer 21

And what are you dividing? What expression?

Answer 22

I did tan(67)times 6

Answer 23

No, that's not the correct expression.

Answer 24

@Hero 2.5?

Answer 25

I did tan(67) divided by 67=0.03, then I did tan(67) divided by 6=0.39

Answer 26

then I added 0.03+0.39=0.42, so 0.42(6)=2.52, rounded to 2.5

Answer 27

You should get paid tutoring. You don't separate the tan from the 67 ever. tan(67) is one thing, not two things to separate.

Answer 28

@Hero 0.4?

Answer 29

Nope

Answer 30

so, its not 2.5 either?

Answer 31

You should be in a real classroom instead of online. It doesn't help you. You need real teachers who can show you things that online classrooms can't.

Answer 32

What you do is this:

Answer 33

Choose your angle: (67 degrees). The side opposite this angle is 6. The side adjacent is \(x\).
\(\tan(67^{\circ}) = \dfrac{6}{x}\).

Multiply both sides by \(x\) to get:
\(x\tan(67^{\circ}) = 6\)

Next divide both sides by \(\tan(67^{\circ})\) to get

\(x = \dfrac{6}{\tan(67^{\circ})}\)

Now you've isolated \(x\). Enter the expression \(\dfrac{6}{\tan(67^{\circ})}\) to your calculator.

Answer 34

I got 3.6

Answer 35

That still is not correct.

Answer 36

At this point, I am unable to help you further.

Answer 37

I did 6/tan(67), like you said, and got 2.54, round to 2.5

Answer 38

Correct. Finally

Answer 39

I have no idea what other mistakes you made along the way but you finally got it.
