Which of the following is a solution to the inequality below? 10b≤ 59
A.) b=2
B.) b=7
C.) b=11
D.) b=9

A.) b=2

Step-by-step explanation:

10b ≤ 59

Divide both sides by 10.

b ≤ 5.9

Any number that is 5.9 or less than 5.9 is a solution.

The only such number in the choices is 2.

A.) b=2

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°
