Hi, I posted this on the 15th and never got any help. Thanks for your help in advance:
(1) Degrees are not the only units we use to measure angles. We also use radians. Just as there are \(360^\circ\) in a circle, there are \(2\pi\) radians in a circle. Compute \(\sin \frac{\pi}{6}\) where the angle \(\frac{\pi}{6}\)is in radians.
(2)Find the length AC, to two decimal places.

Post code to find image in TeXeR:
[asy]
unitsize(2 cm);
pair A, B, C;
A = dir(40);
B = (0,0);
C = (3,0);
draw(A--B--C--cycle);
label("$A$", A, N);
label("$B$", B, SW);
label("$C$", C, SE);
label("$3$", (A + B)/2, NW);
label("$7$", (B + C)/2, S);
label("$50^\circ$", B + (0.5,0.15));
[/asy]
(3)Find the length BC, to two decimal places.

Post code to find image in TeXeR:
[asy]
unitsize(1 cm);
pair A, B, C;
A = 4*dir(71);
B = (0,0);
C = (5,0);
draw(A--B--C--cycle);
label("$A$", A, N);
label("$B$", B, SW);
label("$C$", C, SE);
label("$8$", (A + C)/2, NE);
label("$61^\circ$", A + (0.2,-0.8));
label("$43^\circ$", C + (-0.8,0.3));
[/asy]
NOTE, FOR SOME REASON, THE LATEX IN THE CODE IS RENDERING .... IF (and probably when) YOU PASTE TO FIND THE ANSWER, YOU MAY NEED TO FIGURE OUT *or you could just edit/take it from this post directly* WHAT THE ACTUAL CODING IS TO GET THE IMAGE CORRECTLY.... Thanks!
Thank you for your help in advance.
