Draw arcs on either side of a given point on the line
To construct a line perpendicular to another line through a point on the line:
Measure a length from that point to one edge of the line
Draw two intersecting arcs on either sides of the line
Draw a straight line from the intersecting point of the arcs to the point on the existing line.
The new line drawn is a perpendicular line.
The only step necessary out of the given choices is "Draw arcs on either side of a given point on the line"
Option C is the correct choice

Answer:
443.2m
Step-by-step explanation:
Given in the question that,
distance from building to me = 45m
angle of elevation = 82°
building is 123 m + x m high
If we closely observe then this situation make a right angle triangle and we will use trigonometry identity to solve the question.
Step 1
tan(82) = y / 45
y = 45tan(82)
y = 320.2 m
Step 2
Hence the height of building is y + 123m. So, plug the value of y in this
320.2 + 123 = 443.2
