In a scalene triangle the smallest angle is 10 less than the middle angle. the largest angle is twice the middle angle. find the measures of each angle

Three angles of a triangle add to 180 degrees

 

middle angle = m

smallest  = m-10

largest = 2m

 

add 'em     m-10   +  m  + 2m = 180

                4m -10 = 180

                  4m = 190

                    m = 47.5 degrees

                    smallest = m-10 =   37.5 degrees

                    largest = 2m = 95 degrees
