The first sequence rule is multiply by 2 starting from 6. The second sequence rule is add 4 starting from 16. What is the first number that appears in both sequences?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

honestly bro aint no one got time to answer these dumb question just do it p***y
