Two Angles of a triangular sail measure 65 degrees nd 40 degrees what is the measure of the third angle sail ?

75 degrees

Since the sum of the interior angles of a triangle equal 180 deg, if x is the third angle, then:
180 = x + 45 + 60
180 = x + 105
x = 180 - 105
x = 75 degrees ANSWER
180 = x + 45 + 60
180 = x + 105
x = 180 - 105
x = 75 degrees ANSWER

I'm pretty positive it's 75 degrees :) haha I'm in 8th grade but I'm in advanced math :) I got the highest math grade in the whole grade! :D

180 - 40 - 65 = 75
