For the equation x2 + 2x − 8 = 0, what is the sum of the solutions?

The answer would be x=2 or x=−4

Step-by-step explanation:

⇒x2+2x−8=0

⇒Factor left side of equation,

⇒(x−2)(x+4)=0

⇒Then, Set factors equal to 0

⇒ x−2=0 or x+4=0

⇒ Therefor, the answer is x=2 or x=−4

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°
