Step-by-step explanation:

Given

The Attached Number Line

Solving (a): The Inequality

i. On the number line, we notice that a thick line starts at number 3 and points to the right

ii. Also, there is a closed circle on number 3.

(i) & (ii) indicates that

Solving (b): Set Notation

The set notation that indicates is

Solving (c): The interval notation

The inequality implies that x starts from 3 and moves towards +infinity

The means that 3 is inclusive of the inequality

Hence:

The interval notation is

77

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°
