Put these numbers in descending order. 1.) 0.059

2.)0.01

3.) 0.046

4.) 0.098

4 , 1 , 3 , 2

Step-by-step explanation:

we know since the first value  is the same they are both 0 but the second value is different so we descend it from that order

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.
