Monique and Roger will go skiing only if the temperature drops by 5 degrees Celsius. Currently, the temperature is 3 degrees Celsius. Which of the following shows how cold it must be, in degrees Celsius, for them to go skiing? A.
3 - 5 = 3 - (+5) = 8

B.
3 - 5 = -(3 + 5) = -8

C.
3 - 5 = 3 + (-5) = -2

D.
3 - 5 = 5 - 3 = 2

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.

is it 35
