Answer:
Step-by-step explanation:
One is given the following equation;
The problem asks one to find the roots of the equation. The roots of a quadratic equation are the (x-coordinate) of the points where the graph of the equation intersects the x-axis. In essence, the zeros of the equation, these values can be found using the quadratic formula. In order to do this, one has to ensure that one side of the equation is solved for (0) and in standard form. This can be done with inverse operations;
This equation is now in standard form. The standard form of a quadratic equation complies with the following format;
The quadratic formula uses the coefficients of the quadratic equation to find the zeros this equation is as follows,
Substitute the coefficients of the given equation in and solve for the roots;
Simplify,
Therefore, the following statement can be made;
<em>Height of the pole (DC) is 57.2709m</em>
Step-by-step explanation:
Here, Wire DA and Wire DB supports a pole.
Given that Angle, A=54 , B= 72.
Also, AB = 23m
Now, Taking triangle BCD and Using basic trigonometry
Height of pole H = DC
Now, Taking triangle ACD and Using basic trigonometry
From figure, we know that
AC = AB + BC
AC - BC = AB = 23
Replacing values of AC and BC
Now, TanB= Tan72 =3.0776 and TanA = Tan54=1.3763
Thus, Height of thepole is 57.2709m
