I need help with this question:



I'm sure it's quite easy, but I totally forgot how the teacher explained it. I'm not so much asking for the answer, but how to actually get the answer.

Thanks

We do have to use Sin/Cos/Tan or the inverse, but I forget how...

sin x = .45/6.1

take the inverse sine of whatever .45/6.1 happens to be.

SOHCAHTOA!!!

since the values are on the oposite and hypotenuse side from the angle in question, use sine.

So that would be: Sine^-1 (.45/6.10)

(What IronBeast just said, im just explaining it :p)

you ever hear of Soh Cah Toa? some "native american" chief or something my teacher told us....Sine- opposite/hypotenuse. Cosine- adjacent/hypotenuse. Tangent- opposite/adjacent...Soh Cah Toa. easy, right?

my guess is 15 cuz if the right angle is 90 the other looks to be a tad smaller and then that leaves a 15 or sumthing under 20 for the missing one

if u had a scientific calculator u could just use a formula and some trig stuff
Just because I play the drums doesn't mean I suck at guitar, or ams that I's iz stoopidz.

um lol you can't really do that with math when you need a direct answer. If you were constructing a building could you just eye things? No.

yes i could i would just get a poorly constructed thing that almost looks like something

I did the question, the answer is 4 degrees. Close though...

Sine = opposite / hypotenuse

Sine = .45 / 6.1

Sine = .0737

Now to find the angle, do sine inverse, which is sine^-1

Sine^-1 of .0737 = 4.22 degrees.
