Square root n+5- square root n-10 =1

 sqrt(n+5)-sqrt(n-10)=1 One solution was found :                        n = 59
Radical Equation entered :

     √n+5-√n-10 = 1

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
