Answer 1

@mertsj @mathmale @RadEn

Answer 2

11.53??

Answer 3

Are you familiar with SOHCAHTOA?

Answer 4

I've heard of it, something with cos, tan and sin

Answer 5

Yes, you're right.

SOH: sin = opposite/hypotenuse
CAH: cos = adjacent/hypotenuse
TOA: tan = oppostite/adjacent

Have you worked with sin cos and tan before?

Answer 6

Yes

Answer 7

Alright, so, in terms of angle y, we have the values 20 (the hypotenuse) and 4 (opposite). So what are we going to use here? Sin, cos, or tan?

Answer 8

Sin
Don't you do 4 / 20 and then press sin on the calc?

Answer 9

Yes, but make sure it's sin^-1, or you're going to get a .00000something number

Answer 10

11.53695903 round to 11.53

Answer 11

You're going to round that to 11.54, actually

Answer 12

Can you check this one too? Solve for x

Answer 13

So it's opposite and adjacent so you use tan. 61.92751306

Answer 14

It should be 28 degrees.

\[\tan^-1(\frac{ 8 }{ 15 })\]

Answer 15

When finding angles you have to remember to use the ^-1 instead of just the function

Answer 16

so it's 8 / 15 not 15 / 8

Answer 17

Yes

Answer 18

Exact answer would be 28.07?

Answer 19

From 28.07248694

Answer 20

Thanks!
