Its 125 It cant be 25 or 29 because the angle is clearly obtuse And Angle MPQ is the same as LMN If you take 125 and subtract 50 from it (because you need to add 50 to 3x) you get 75 After that you need to divide 75 by 3 because 3 is multiplied by x You should get 25 Therefore X=25 If X=25 then 5x is 125
