- anonymous

um i think i am doing it right.

- anonymous

okay than where did 180 come from?

- anonymous

I did to know the whole problem not just answers

- anonymous

180 is the total of the 3 angles of the traignle

- anonymous

since i know A=32 and C=77 B= 71 from 180-32-77

- anonymous

did you plug for for these?

- anonymous

did you a and put in it for a

- anonymous

the formula to find an area of a triangle with 2 angles and one side given is area= a^2sinBsinC / 2sinA

- anonymous

so i did like this

am i wrong or is this book stupid...? lol

- alexwee123

im just curious
is this geometry or trig? o.0

- anonymous

its in trig.

http://www.regentsprep.org/Regents/math/algtrig/ATT13/areatriglesson.htm
it gives a better formula and solution :D

ok ok...i think u should try to change your calculator settings to degrees and not radians!

- anonymous

its in degrees...i already tried doing that...

- anonymous

what is the answer?

- anonymous

wait a seocnd...i'll put my numbers up...i got approximately 170.3...check for yourself...

- anonymous

in other words sub in

- anonymous

wait how did you get 180.57.?? i cant got 188.36

- anonymous

ok...lets take even more baby steps! what did u get for sin71 x sin77?

- anonymous

cfraser should I go and let you help or stay??

- anonymous

i can help...i guess...!

- anonymous

sin77= 0.9744 sin71= 0.9455

- anonymous

im so sorry ><

- anonymous

y?

- anonymous

for making you guys have a hard time....

- anonymous

nah don't worry about it

what did u get for 2sin32?

- anonymous

ha ha typo wow get love trig on a computer ha ha

- anonymous

2sin32 = 1.0598

- anonymous

okay...so, divide those two numbers!

- anonymous

dont round them up like me! the more digits...the better!!
