A scientist estimates that a jet of liquid iron in the Earth's core travels 9 feet every hour. Using this estimate, you find that liquid iron travels 432 feet in 1 day.
The scientist later states that the iron travels 3 feet every 10 minutes. Does this
change your answer about how far the liquid iron travels in one day?

27 inches

Step-by-step explanation:

To find the length of the diagonal, we just need to use the cosine relation of the 48° angle.

The adjacent side to the angle is the height of the canvas, and the hypotenuse formed is the diagonal of the canvas. So, we have that:

cos(48) = height / diagonal

0.6691 = 18 / diagonal

diagonal = 18 / 0.6691 = 26.9 inches

Rounding to the nearest inch, the diagonal of the canvas measures 27 inches
