If two angles of a triangle measure 43 degrees and 48 degrees the triangle is

The Triangle is Acute.

If 2 angles measure 43 and 48 ... then the third angle measures (180 - (43 + 48) = 89 ... so ur 3 angles are 43, 48, and 89 ... because the angles of a triangle add up to 180 degrees.

This is an acute triangle ... an acute triangle is a triangle that has all 3 angles that are less then 90 degrees each.
