Plzzz
select the equation of the line that passes through the point (2, 6) and is perpendicular to the line x = 4.

y = 4
y = 6
x = 6
x = 2

In the points (2, 6)
2 is on the x axis and 6 is on the y
Now plot x=4 on the gragh until the two become perpendicular
Y=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
