Which set of angle measures could be the measures of the interior angles of a triangle?
90°, 42°, and 58°
60°, 60°, and 60°
100°, 48°, and 42°
31°, 75°, and 70°
it's b
the sum of a triangle's angles is always equal to 180 degrees
as you see the second option (60, 60, and 60) is equal to 180 so it's b (aka second option)
next sum >180 no way
last sum < 180 no way
Its timed and got 7 mins left please hurry someone
90+42 + 58 > 180, no way
60 60 60 is 180, plain old equilateral triabgle
