Question

What is the value of x rounded to the nearest hundredth?

Answer 1

Have you considered the Tangent Function?

Answer 2

i dont know how to do it :/

Answer 3

Why? You should not be given a problem with no tools to solve it.

You should have this: \(\tan(\alpha) = \dfrac{Opposite}{Adjacent}\)

You should have this: \(\cos(\alpha) = \dfrac{Adjacent}{Hypotenuse}\)

You should have this: \(\sin(\alpha) = \dfrac{Opposite}{Hypotenuse}\)

Do you have these definitions?

This brings to mind that I must have been sleeping when I said "Tangent". Sine would be the right one. Sorry about that.

Answer 4

ok so.. sin49=x/55?

Answer 5

Perfect. Now what?

Answer 6

im not sure

Answer 7

to solve for x you would multiply both sides by 55?

Answer 8

Since 49º is not a convenient number, you'll just need a calculator that can do it.

Answer 9

Yes, multiplying by 55 will solve for x, but you still need a numerical value for \(\sin(49º)\).

Answer 10

how do i get t?

Answer 11

Do you have a calculator with a "sin()" button? There are plenty online calculators.

Here's one: http://web2.0calc.com/

There are many more.

Answer 12

so do i put in sin(49) and see what it gives me?

Answer 13

Yes. If you get -0.953752652 then you have to do something else. That is a possible incorrect answer if you are not familiar with your calculator.

Answer 14

i got 41.509

Answer 15

Excellent. One more thing. We have not quite answered the question. What are we missing?

Answer 16

im not sure?

Answer 17

What are the rounding requirements?

Answer 18

to the nearest hundredth ...so its..41...im not sure

Answer 19

41.509 is rounded to thousandths.
41.51 is rounded to hundreths.

Answer 20

ok i see

Answer 21

NOW it's done. Good work.
