Please answer asap!! need to find the solutions to this equation.

The answer to your question is the letter d. k = -7/2 and k = 7/2

Step-by-step explanation:

Equation

                         4k² - 49 = 0

Process

1.- Add 49 in both sides

                        4k² - 49 + 49 = 49

2.- Simplify

                       4k² = 49

3.- Divide by 4 both sides

                       4k²/4 = 49/4

4.- Simplify

                         k² = 49/4

5.- Get the square root in both sides

                      √k² = √(49/4)

6.- Simplify

                         k = ± 7/2

   or     k₁ = 7/2                            k₂ = -7/2          

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

it is x=-4
