geometry - how do i find ? is it cos?

[elfin cairn]

how can i find c?

no value is for adjacent so idk what to do to find c

SOHCAHTOA works for any angle in a right triangle if that angle is not 90 degrees. Apply the same logic as you would if you were given the measure for angle CRA (you could also just solve for the measure of that angle if you'd like to use it instead).

i dont really understand

ive been using soh cah toa but theres no measure theres no length there

[glad canopy]

Let's just keep it simple and use angle ACR, since it is already given. Refer to this chart to help you.

In terms of the angle which has a measure of 59, what are the relationships of the side lengths labeled "15" and "c", respectively?

[elfin cairn]

sin(59) = c/15?

just to confirm

[glad canopy]

Correct!

Now isolate c.

[elfin cairn]

12.86?

for c?

[glad canopy]

Yep, don't forget to round to the nearest tenths place.

[elfin cairn]

so 12.8

oh wait

12.9

ah thank you so much

I really appreciate it!
