The force of gravity on the moon is approximately one sixth that of the earth. the direct variation formula for weight on the earth compared to weight on the moon would be e = 6m, where e = weight on the earth and m = weight on the moon. the space suit that an astronaut wears while making a moon walk would weigh approximately 90 pounds on earth. what would be the weight of a 180 pound man wearing a space suit on the moon

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.

it's the only multiple of both and the least
