Given triangle wet where angle r is a 40 degrees the measure of angle q is 60 less than the measures of angle conclusion what is the measure of angle t
a triangle's angle sum is 180 degrees, so you would subtract 180-60=120 because angle q is 60 degrees less than 180. now add 40 to 120 to equal 160 then subtract 160 from 180 to equal 20 degrees
