Find \$AC\$ in the following triangle, to two decimal places.

[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("\$1\$", (A + B)/2, NW);
label("\$3\$", (B + C)/2, S);
label("\$40^\circ\$", B + (0.5,0.15));
[/asy]

I just need confirmation what i'm doing is correct.

hi Geometry Help

Welcome to the forum.

I'd like to help but I cannot understand your notation.  I have got no hits by searching for [asy].  I've tried drawing a diagram as follows:

1.  Mark coordinate axes.

2. Plot B (0,0) and C (3,0)

3. Draw a line from B to A (unknown position) so that angle ABC = 40 degrees.

Then I'm stuck.

Please would you re-post with a written description of the diagram, like the one I have put here.

Thanks,

Bob
