Respuesta :

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.
The Triangle is Acute.
