Iam a 2 digit number. i am the difference of two numbers whose sum is 36. the larger of these numbers is twice the smaller. what number am i?

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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°
