The point-slope form of a line is:
y-y1=m(x-x1), where m is the slope of the line and (x1,y1) is any point on the line.
In this case x1=7 and y1=-2 so the point used to create this equation is:
(7, -2)
Answer:
1064 ft.
Step-by-step explanation:
Start by sketching out a figure to represent the situation, it should look something like this:
(See picture)
(Figure definitely not drawn to scale)
The angle marked in red measures 4.3°, then we can use the law of sines to solve for the height of the Eiffel Tower (represented as the variable x):

Rounding gives 1064 ft.
Corresponding sides of the two triangles occur in a ratio with one another. In particular, you have the relationship

We only need the first two parts to solve for

Money spent on lawn mower: $360
He has $840-$360=$480
Money spent on gift: $60
He now has $480-$60=$420
Hope this helped! :)
