The sum of interior angles of a triangle must add up to 180 degrees
if the triangle has an angle that is greater than 90 degrees, then it is considered obtuse
if the triangle has an angle that is 90 degrees, then it is considered right
if all angles are less than 90, then it is acute
find the missing angle "x"
180=60+80+x
is angle x less than, greater, or equal to 90 degrees?
Isolate the variable by dividing each side by factors that don't contain the variable.
