Irene mowed the lawn and planted flowers The amount of time she spent mowing the lawn was 1/3 the amount of time it took her to plant flowers. It took her 30 minutes to mow the lawn. Let P represent the amount of time she spent planning flowers. Find the amount of time Irene spent planting flowers.

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.
