What is the value of x in the equation 4(2x + 10) = 0? 1) −5 2) −7 3) 5 4) 7

the answer is 1) -5

404.9 ft

Step-by-step explanation:

The information given is illustrated in the diagram attached below. We have a right triangle.

We have the following:

Angle of elevation = 39°

Adjacent side = 500 ft

Opposite side, which is how high the bird is flying over the school = h

Apply the following trigonometric ratios:

Plug in the values

Multiply both sides by 500

404.9 = h (nearest tenth)

✅The bird is flying at about 404.9 ft high over the school.
