How do I write log7t as a base 2 logarithm?

Given:

The value is .

To find:

The value as a base 2 logarithm.

Solution:

We know that,

where, a is any positive value.

We have,

Using the above property of logarithm, we get

For a=2,

Therefore, the given value as a base 2 logarithm can be written as .

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°
