Write an inequality to describe the possible values of x.

x = 9.934

Step-by-step explanation:

Law of sines: a/sin A = b/sin B = c/ sin C

10/sin (5x-10)° = DE/sin ∠DCE    (in ΔDCE)

12/sin 50° = AB/sin ∠ACB

AB=DE     ∠DCE = ∠ACB    DE/sin ∠DCE = AB/sin ∠ACB

10/sin (5x-10)° = 12/sin 50°

sin (5x-10)° = 10/12 * sin 50° = 5/6 * sin 50° = 5/6*0.766 = 0.638

5x - 10 = 39.67

5x = 49.67

x = 9.934

X has a value, if that's not correct... just report it.

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.
