Which of the following is the contrapositive of the conditional below? if 3 + 4 = 6, then 2 · 5 = 10. a. if 2 · 5 = 10, then 3 + 4 = 6. b. if 3 + 4 ≠ 6, then 2 · 5 ≠ 10. c. if 2 · 5 ≠ 10, then 3 + 4 ≠ 6. d. if 3 + 4 ≠ 6, then 2 · 5 = 10.

If 2 · 5 ≠ 10, then 3 + 4 ≠ 6.

Step-by-step explanation:

Because a contrapositive is the contradiction the hypothesis and conclusion of something given and interchanging them. For example: "if not-B then not-A " is the contrapositive of "if A then B "

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°
