Is the relation between the number of quarts picked and the weight of the strawberries proportional?Explain.

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.

47 - 90 = 43

43 - 180 = x

x = 137

believe it or not anna is correct good job anna give me a fist bump there u go gal
