Answer:
The correct answer is 144.
Step-by-step explanation:
The librarian noticed that 60% of total seventh graders checked out fantasy books from the library.
Total number of seventh graders is given to be 240.
Number of seventh grade students who checked out fantasy books = 60% of 240 = 0.6 × 240 = 144.
Thus out of 240 seventh graders 144 of them would check out a fantasy book from the library.

Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.
x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)
(πrθ)/180 = arc length [r=radius, θ=central angle, π≈3.14] ⇒
πrθ = 180*arc length
θ = (180*arc length)/πr
θ = (180 * 50)/(3.14 * 36) ≈ 79.6°
Sam would have paid 55 dollars. Since the sales tax is 10%, you would find 10% of 50, which is 5. Then add five to the 50 dollar wagon price to find the total cost of 55 dollars.
