Total consumption of fruit juice in a particular country in 2006 was about 1.96 billion gallons. The population of that country in 2006 was 500 million. What was the avergae number of gallons of fruit juice consumed per person in the country in 2006?

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.

your correct answer is c. he organized a political resistance group based on islam.

im sorry for the poor quality answer.
