F(x) = x2 + 1 g(x) = 5 - x
(f + g)(x) =
O
x + x -4
O x + x + 4
07 - x + 6
O x + x + 6

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
