We can use trigonometry to solve this problem. Let's draw a diagram to help us visualize the situation:
X

P
We know that the angle of elevation of X from P is 60 degrees, which means that the angle XPX' is also 60 degrees, where X' is the foot of the pole. We also know that the distance from P to X' is 55m.
Let H be the height of the pole. Then we have:
tan 60 = H / PX'
We can simplify this expression using trigonometric ratios:
√3 = H / 55
Solving for H, we get:
H = 55√3
Therefore, the height of the pole is 55√3 meters. So the correct option is (c).
Question 30 Report
Answer Details
To find the value of q, we need to solve the given system of equations:
3p - q = 6 ...(1)
2p + 3q = 4 ...(2)
One way to solve this system is to use the method of elimination, where we eliminate one of the variables by adding or subtracting the equations.
Multiplying equation (1) by 3, we get:
9p - 3q = 18 ...(3)
Now, we can eliminate q by adding equations (2) and (3):
2p + 3q = 4
9p - 3q = 18
-----------
11p = 22
Dividing both sides by 11, we get:
p = 2
Substituting this value of p in equation (1), we get:
3(2) - q = 6
Simplifying this, we get:
6 - q = 6
Subtracting 6 from both sides, we get:
-q = 0
Dividing both sides by -1, we get:
q = 0
Therefore, q = 0 is the solution of the given system of equations.
In summary, to find the value of q, we used the method of elimination by multiplying equation (1) by 3 and adding it to equation (2) to eliminate q. This resulted in finding the value of p as 2. Substituting this value of p in equation (1), we found the value of q as 0.
