3) Tommy is drawing a triangle with angles measuring 41° and 123°, and the included side measures 6 cm. What is the measure of the third angle of the triangle? A) 16° B) 57° C) 139° D) 196°
The answer I believe would be "D", the full shape of the triangle should add up to a total of 360 degrees, so adding "123" and "41" comes out to "164" So then you would just see which of the options would add up to 360.
