Use Euclid's division lemma to show that the cube of any positive integer is of the form 9m,9m+1 or 9m+8. In this question, why do we take a=3q, a=3q+1 and a=3q+2. why cant we take a=2q and a=2q+1. or a=5q, 5q+1, 5q+2, 5q+3 and 5q+4. why do we specifically use a=3q and 3q+1 if a is any positive integer and can be represented in other ways?

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
