Answer:
Step-by-step explanation:
Given that,
The height of a cell tower, P = 70 m
The tower casts a shadow of 45 meters on the ground.
We need to find the angle of elevation of the shadow to the top of the cell tower. We can use trigonometry to find it.
Put all the values,
Hence, the angle of elevation is equal to 
.
Answer:
Alex can line eight 1-meter wide with the paper.
Step-by-step explanation:
- Alex has five rolls of shelf paper that is 800cm.
- She wants to use the paper to line the 1-meter wide shelves in her pantry.
- We want to determine how many 1-meter wide she can line with the paper.
- First, we know that
100cm = 1m
- we need to determine how many meters are in 800cm.
100cm = 1m
800cm = xm
100x = 800
x = 800/100
= 8
Therefore, 800cm is equivalent to 8m
Alex can line eight 1-meter wide with the paper.
