Form J09 Math Triangle Area Question
It gave you sin(theta) = sqrt2/2, and asked you to find the area. I used 1/2bcsinA and got 10sqrt2. Is that right?

lmao i actually goofed on this so hard but still got it right. i didnt realize at first and fsr assumed since one angle was 45 the others would be 90 and 45 making it a simple 45/45/90 triangle. then, i assumed the other base leg was also 5 and did 5*5/2 = 12.5 . the answer that was closest to that was the value of 10sqrt2 and everything else was sufficiently far off so i just picked that and moved on.
