(Marking brainliest) Please help asap! Questions are in the pdf, and please let me know which is question one and which is question 2, thank u.

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.

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

y + 11 = (1/4)(x + 16)
