Use similar triangles
distance of man from puddle = 0.5 m.
distance of puddle from tower = 13 - 0.5 = 12.5 meters
so we have 2 similar triangles
one has height 2 m and base 0.5 m and the other has height x m ( the tower) and base 12.5 m
Corresponding sides are in the same ratio, so
2 / x = 0.5 / 12.5
0.5x = 2*12.5 = 25
x = 25 / 0.5 = 50 m
The tower is approx 50 m high.
Some schools do this differently, but since I don’t have any of the answer choices I’ll show you how to
Factor: -6|x+5|-2
Factor out the two
2(-3|x+5|-1)
And if you are looking for a graph here:
Answer:The height of the building is 30ft
Step-by-step explanation:
2a.) 8.8 x 8.8 = 35.2g
2b.) 35.2 x 30 = 1056g or 1.056kg
