Help With drawing trig bearing?

Radar stations A and B are 9.2 km apart and station B is on a bearing of N 76° E relative to station A. Station A detects an airplane at a point C on a bearing of S 55° E. Station B detects the same airplane on a bearing of S 35° W. Find the distance of the airplane to both stations.

I understand how to solve this, but can someone help me draw? When I draw I get a triangle with angles 35, 14, 90 which cannot be right since triangles are 180 degrees.

    Angle A = 49 deg, angle B = 41 deg, angle C = 90 deg.

    AC = (9.2 km)*sin(41), BC = (9.2 km)*sin(49).
