Answer:
I have that same problem but im trying to figure out the answer
Step-by-step explanation:
Answer:
above the sea level means height than the sea and below sea level means lower than sea height
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.
Answer:
1.-9x^2
2.16x^4
3.x^2+4x
4.x^2+4x+4
5.x^2-x-12
6.x^4+2x^3-4x^2
