Answer 1

\[A=\frac{1}{2}bc\sin(\alpha)\]

Answer 2

in your case \(b=c=12,\alpha=22\)

Answer 3

okay so A=1/2(b)(12)(22) ?

Answer 4

does c=12 also?

Answer 5

i got 26.98 is that right?

Answer 6

\[\frac{1}{2}\times 12\times 12\times \sin(22)\]
\[72\sin(22)\] then a calculator

Answer 7

okay then i did it right thanks!

Answer 8

yes i got the same answer, 26.97 rounded
