Aparallelogram, which is not a rectangle, has three of its consecutive vertices given by a(1, 2, 4), b(2, 0, 5) and c(4, 6, 0). the line through the points a and e intersects the line through b and c at a right angle. depending on whether point e falls between b and c or not, there are two pictures possible, as shown be

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
