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 .
The inequality expression to represent the situation is m ≤ 7
<h3>What are inequalities?</h3>Inequalities are expressions that are not separated by an equal sign.
- the inequality signs are <, >, ≤ and ≥
If Charmain must run a mile in 7 minutes or less to beat her best time, this can be expressed in inequality form as;
m ≤ 7 where:
- "m" represents the number of minutes Charmain must run.
