Fan, medal, testimony

Answer 1

I got C

Answer 2

we can do this, you need to find two distances, from one wall to the source and from the other wall to the source
you supposed to use trig?

Answer 3

iirc, the ratio for a 30-60-90 is 1:rt(3):2

Answer 4

@satellite73 I think so yeah. this in my geometry class but in this current assignment I have trig problems

Answer 5

C is correct. By solving , I got 180/sqrt(3) which is 60sqrt(3)= 103.92

Answer 6

\[\tan(60)=\frac{60}{x}\iff x=\frac{60}{\tan(60)}\]\[\tan(30)=\frac{40}{y}\iff y=\frac{40}{\tan(30)}\]

Answer 7

you don't really need trig for these you can use the triangle ratios too as done above

Answer 8

oh okay, so I was right?

Answer 9

what is your answer?

Answer 10

C

Answer 11

actually you don't have to do any work to solve this
95% of the time the answer is C, and it is C here too
