Question

!!!!Cosines / sines . Find a and round to the nearest 10th.

Answer 1

I think Erica said I messed this one up. It looks the same. Oh yeah I think this was the one I thought
`a=1.8=3√(2)-√(6)`, Answer: 1.8.

Let's do it again.

`(a)/(\sin(180 - (15+105)))=(2)/(\sin 105^\circ)`

`a = (2 \sin(60))/(\sin 105^\circ)`

`a \approx 1.8`

Yes, same as before.
