A triangular lots sits at the corner of two streets that intersect at an angle of 58º. One street side of the lot is 32 meters and the other side is 40 meters. How long is the back side of the lot (the third side) to the nearest meter?

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.

3; 9 is 8 to -4

step-by-step explanation:

c) yes, because of asa or aas

28
