Answer:
x = -1 +/-2i
Step-by-step explanation:
Write the equation in standard form to find the roots, also known as the solutions, zeros, or x-intercepts, of the quadratic.
x² + 2x + 5 = 0
Use the quadratic formula by substituting a= 1, b = 2 and c = 5.
The wall and ground make a 90 degree angle. You don't need the 13 feet at all and that is the hypotenuse it uses the wall and ground distances so its tangent because tangent is the only trigonometric function that doesn't use the hypotenuse.
