Question

Determine the length of RS to the nearest tenth of a meter. Show the steps and your work.
Thank you!

Answer 1

Do you know which trig ratio you can use in this problem?

Answer 2

can you please show me this step by step.
thank you

Answer 3

No worries



\[cos \theta=\frac{A}{H}\]\[sin \theta=\frac{O}{H}\] \[tan \theta=\frac{O}{A}\]

Which one do we have enough information to use?

Answer 4

tan

Answer 5

?

Answer 6

lol i suck in trig also sorries

Answer 7

Not tan. We know theta and which side do we know, O, H or A?

Answer 8

adjacent?

Answer 9

i mean a

Answer 10

cos(17) = 18.8/RS

RS = 18.8/cos(17)

Answer 11

Perfect. We know adjacent since it is the side that touches the angle. So the trig ratio we'll use is cosine.

Answer 12

BaileyC does this make sense or would you like me to explain it differently?
