66 divided by 3 = 22 which equals 1/3 of the tickets. So 2/3 = 44. The 44 children's tickets minus the total tickets sold = 22. The total number of adult tickets sold were 22.
Answer:
The value of x is 17°.
Step-by-step explanation:
The two exterior angles on the same side of the transversal are always supplementary.
Therefore, if the measure of two exterior angles on the same side of the transversal are 3x and 7x+10, then we can write
3x + (7x + 10) = 180°
⇒ 10x = 180° - 10° = 170°
⇒ x = 17°
Therefore, the value of x is 17°. (Answer)
Answer is : -7
Reason: 5(-2)=-10
-10+3=-7
