Order these numbers from least to greatest; 2/7, 0.25, 5/2, 0.2, 0.

0.2, 0.2, 0.25, 2/7 , 5/2

Step-by-step explanation:

First convert the numbers to decimal form:

2/7 = 0.29, 0.25, 5/2 = 2.50, 0.20, 0.20

Then arrange the numbers from least to greatest;

0.20, 0.20, 0.25, 0.29, 2.50

Finally convert back to initial state (in the order of least to greatest);

0.2, 0.2, 0.25, 2/7, 5/2.

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°
