Best ResponseYou've already chosen the best response.2[if two angles add to 180° they are called supplementary , (not equal)]

Best ResponseYou've already chosen the best response.2What angle is alternate to angle D, the 65° angle? can you mark it on the diagram

Best ResponseYou've already chosen the best response.2so we have all the angles in this triangle : dw:1439962315847:dw

Best ResponseYou've already chosen the best response.0oh can i do 40+65 = 105 and subtract that to 180 to get x?

UnkleRhaukus

Best ResponseYou've already chosen the best response.2and we know that the three angles in any triangle are supplementary: \[\angle CAB+\angle ABC+ \angle BCA = 180°\\ 40°+65°+x=180°\\ x=180°(40°+65°)\\ x=180°105°\] (exactly)
