the height of the building in part a
tan theta = y/x
y1 = tan theta x
= tan35 * 85
=59.51 m
the height of the building in part b
tan theta = y/x
y2 = tan theta x
= tan38 * 85
=66.4m
the height of the antenna is
dely =y2- y1 = 66.4 m - 59.51 m = 6.88 m

A superhero is running toward a skyscraper to stop a villain
from getting away. As he is moving, he looks up at the top of the
building and his line of sight makes a 33.0° angle with the ground.
After having moved 350 m, he looks at the top of the building
again, and notices that his line of sight makes a 52.0° angle with
the horizontal. How tall is the skyscraper?
the horizontal distance between the persons eyes and the
building is 85m. in part a
