Solve (x +9)2 = 25.
1. Apply the square root property of equality:
2. Isolate the variable.
V(x + 9)2 = 1,25
If x + 9 = 5, then x = 1
If x + 9 =-5, then x=

Step-by-step explanation:

We have been given the equation

and we are asked to apply the square root property of equality to our given a equation and isolate the variable

First, take the square root of both sides of our equation

THEREFORE, THERE ARE TWO SOLUTIONS FOR OUR GIVEN EQUATION

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°
