The attributes below are shared by both rhombuses and rectangles

Rectangles and rhombuses are quadrilateral, and they have opposite sides that are parallel and congruent. Opposite angles in rectangles and rhombuses are also equal, since the opposite sides are parallel.

a

Step-by-step explanation:

Based on my calculations, a is our answer becuase 4 sides is in both rhombus and rectangle because b is incorrect because rhombuses do not haVE 4 right angles, in fact they have none. c is also incorrect becase our lines are not proven to be perfectly equal. d is incorrect because a rhombus has uneven lines. anyways a i believe is ur answer! hope this helps

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.
