The equation P= 21+ 2w is used to find P, the perimeter of a rectangle, using the length (1) and the width (w) of the rectangle. What is an equivalent equation solved for w?

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°

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

hi there, i would be interested to you with your test, may you add the questions and answer options.
