value of sin - I need this questions done by 8

[olive relic]

Many thanks if you help

[strong pelican]

sin(x)=opposite/hypotenuse

[hard haven]

Try it once

[olive relic]

Ok

[hard haven]

And write the answer here

[olive relic]

1.38

[strong pelican]

Wait, I don't think this is quite right

[olive relic]

Oh

[hard haven]

Sorry it's perpendicular/hypotenuse

[olive relic]

uh

[hard haven]

I m really sorry

[olive relic]

ok

What’s answer

[hard haven]

Sin(theta) = 13/18

[olive relic]

Ohh

1.38 ye?

[hard haven]

Yeah but you should write it in the fractional form as given in question

[olive relic]

OH

I thought u meant / divide

😝

Oo and what’s B

I’m not good with angles

[strong pelican]

I'm guessing you can use a calculator for that one

[olive relic]

How do u find it out

[strong pelican]

If sin(x)=y, than x=arcsin(y)

[olive relic]

Uh

What’s the answer for that sorry

I rlly bad at this question

[strong pelican]

Find arcsin(13/18) using a calculator

[olive relic]

Uh

Ok

That?

[strong pelican]

Yep

[olive relic]

So 46.23

Now to 1.dp

[strong pelican]

One decimal point

[olive relic]

So it’d be 46.2

[strong pelican]

Yeah

[olive relic]

Thx
