Question

Do the angle measurements 70, 90, 75 make a triangle?

Answer 1

Interior angles of a triangle always add up to 180 degrees, so no.
90 degree is a right triangle and it would have two acute angles. An obtuse triangle would have one angle larger than 90 degrees and two acute angles. An acute triangle would have all angles smaller than 90 degrees.

Answer 2

Yes.

Explanation:

Because the sum of any 2 sides is greater than the third side.
