Answer:

Step-by-step explanation:
From the question we are told that:
Height 
Angle of depression 
Angle of Elevation 
Generally the equation for the vertical distance between Emery's distance x and the bottom of the building is mathematically given by
Since the angle of depression and elevation are given as
27 and 23 respectively
Therefore
Emery's view of the 42 ft building is


Therefore Emery's distance x to the base of the building h' is


Generally the Trigonometric equation for Emery's distance x is mathematically given by



Answer:
Step-by-step explanation:
Finn earns $5 for each crate of oranges he sells in a week. This means that if she sold z crates in a week, the total amount that she would earn is 5 × z = 5z
At the end of the week, Ellie has earned $20 more than Finn. The following expression shows Ellie's earnings :
20 + 5z
Therefore, in the expression, the second term represents the total amount that Finn earned for selling z crates.
No more than in terms of math means less than or equal to.
P = 2l + 2w
{96 ≤ 2l + 2w
{L ≥ w - 4
Here we see a system of linear inequality in two variables.
You finish.
