You are shown \angle OPQ∠OPQ below whose measure is 90°. Draw your best estimate of an angle bisector of \angle OPQ∠OPQ by clicking a dragging a ray out from the vertex at P. To be marked correct, your drawing must be within 5° of the correct bisector.

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.
