The measure of the angles of triangle abc are given by the expressions in the table. angle-measure a-48 degrees b-(6x-28)degrees c- (2x) degrees find the value of x. then find the measures of angles b and c. enter your answers in the boxes. x= m m

Identify a1 and r for the geometric sequence an= -256(-1/4) n-1

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12
