<span>The distance to the base of the tower is
tan 40=100/x
x=100/tan 40=119.18 m
from the top of the building, we know the adjacent side but not the opposite
tan 30=opposite/119.18
opposite is 119.18*tan30=68.81 m
The opposite side is the height of the tower ABOVE the apartment building. The tower itself is 100 m high, and the remainder of the height, 31.19 m, is the height of the building.</span>
Step-by-step explanation:
Given
- 4( 3x - 5 ) > - 28
Dividing both sides by - 4 we get
3x - 5 > 7
Adding 5 on both sides we get
3x - 5 + 5 > 7 + 5
3x > 12
Dividing both sides by 3 we get
x > 4
