land such that ÐCAB = 48.8°. He also measures CA as 318 ft and CB as 523 ft. Find the distance between A

and B. Please round the answer to the nearest tenth.

..pls help me this..

- tri -
**Reiny**, Saturday, October 27, 2012 at 11:32pmI assume you made the correct diagram.

First let's find angle B

sinB/318 = sin48.8/523

sinB = 318sin48.8/523

once you have angle B, we can find angle C

then using the sine law again

AB/sinC = 523/sin48.8

AB = 523sinC /sin48.5

I will leave the button pushing up to you

(I got 674.5)
