Step-by-step explanation:

8x² - 15x + 3) - (20 - 2x) = 8x² - 15x + 3 - 20 + 2x = 8x² - 13x - 17

John stands 150 meters from a water tower and sights the top at an angle of elevation of 36º. If John's eyes are 2 meters above
horsena [70]

Answer:

The height of tower DB=111\ meters.

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that,

Distance between John and tower is  CE=150 \ meters.

Angle of elevation to the top of the tower is \angle DEC=36°.

Height of John is  CB=2\ meters.

To Find: Height of the tower DB.

So,

In triangle ΔDCE,

                    Tan(∠DEC)= \frac{DC}{CE}

                    Tan (36)= \frac{DC}{150}

                     DC= tan(36)\times 150

                     DC=108.98\ meters

Now,

To calculate the height of tower we have

                    DB=DC+CB

                    DB=108.98+2

                    DB=110.98\ meters ≈ 111 \ meters

Therefore,

The height of tower DB=111\ meters.
