please shows solution
let the mid angle be x, then the previous angle is (x-30) and the other angle is (x+30). now, as we know summation of all the angles of a triangle is equal to 180 degrees. so we have (x-30)+ x+(x+30)= 180 or 3x = 180 or x= 60, so now the previous and the upcoming angles will be 30 and 90 degrees respectively.
