Needuse the pythagorean theorem to prove that the three sides of the triangle are the three sides of a right triangle. show all of your work. 2, 4, 2√3 i know that a squared + b squared = c squared but the 2√3 threw me off and the lesson doesn't really go over it so i need asap.

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.

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
