A horizontal line has points A , E, D. A line extends vertically from point E to point C and forms a right angle at C E D. A line extends up and to the left from point E to point B. Which statement is true about the given information?

∠CED measures 45°.
∠CED measures 180°.
∠AEC measures 90°.
∠AEC measures 45°.

  ∠AEC measures 90°

Step-by-step explanation:

Angle AED is a "straight angle", so angles AEC and CED are a linear pair. The angles of a linear pair are supplementary, so angle AEC is supplementary to right angle CED:

  ∠AEC = 180° -∠CED = 180° -90°

  ∠AEC = 90°

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.

step-by-step explanation:

their are no angles. sorry cant .
