Angle A and angle B sums up to 180 (interior angles)
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
angle A = 6(18)-35 = 73 degrees
F(n)=3n-2
Plug in 2 for n. f(2)=3(2)-2=4
on a horizontal number line . numbers to the left are less than numbers to the right .. numbers to the right are less than numbers to the left
