The answer to this equation is negative 6 but I don’t know to explain how I got the answer is word form.

The value of k is –6.

Solution:

Given equation:

To find the value of k:

Using exponent rule:

Using exponent rule:

Using exponent rule:

If the bases are same then, we can equate the powers of the bases.

i. e. If then m = n.

k + 9 = 3

Subtract 9 from both sides of the equation, we get

k = –6

Hence the value of k is –6.

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°
