It added up to i think 260 degrees 35 which rounded up to 261 degrees im pretty sure...it depends whether you used the exact number in the Sin Rule or if you just used 13- StewMcGlinchey

You had to use alternate angles to find the 55 degree angle, and the Sine Rule to Find ACB then add the ACD, 55 and 180...I got 261- StewMcGlinchey
