The sum of the angles in a triangle is 180. Let x be one acute angle and y be the other. We know one is 5 times larger so let’s say 5x = y. Now, x + y + 90 = 180 x + 5x + 90 = 180 6x + 90 = 180 6x = 90 x = 15
B - line graph. A line graph should be added because he wants to know how many of available apartments there were during the time of the year and line graphs are usually up and down on the info.
