Let U be the set of all the positive integers less than 19 Let A be the set of all the even positive integers less than 19 Let B be the set of all the multiples of 3 positive integers less than 19. Define the following sets.
Remark: Note that both A and B are subsets of U. The complement of sets should be defined relative to the set U.
(a) A
(b) B
(c) A
(d) -B
(f) AnB
(g) A\B
(h) B\A
(i) -(AUB)
(j) -(ANB)

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
