Find the measures of the interior angles of a triangle whose two exterior angles equal to 120° and 150° find the answer in this format: the measures of the angles are

30 degrees, 60 degrees and 90 degrees

If one exterior angle is 120, then its interior counterpart is 180-120 = 60.

If another exterior angle is 150, then is interior counterpart is 180-150 = 30

Let x be the missing interior angle. It adds with the other interior angles and all three interior angles of any triangle always add to 180

x+60+30 = 180

x+90 = 180

x+90-90 = 180-90 subtract 90 from both sides

x = 90

So the missing interior angle is 90 degrees

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
