Let a = {the whole numbers} and b = {the integers}. find a ∩ b. 0 the integers the whole numbers the real numbers

The correct answer is THE WHOLE NUMBERS.
Whole numbers refers to numbers starting from zero to any number, but they do not include negative numbers, fractions and decimals. Integers refers to whole numbers but they also include negative number. The intersection between the two refers to the numbers that are common to the the two of them. Thus, in this case the common numbers are the whole numbers, because whole numbers exist in the two groups.

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
