Answer:
It is 42° higher for the observer at 12° north because of the differ- ence in latitude.
Explanation:
The sun's altitude can be given by the following formula:
In which S is the sun's altitude, L is the latitude of the place and D is the declination of the sun.
Since the comparasion occurs at the same day, the value of D will be the same for both cases, so it can be disconsidered in our calculation.
First observer
Second observer:
The correct answer is:
It is 42° higher for the observer at 12° north because of the differ- ence in latitude.

Determine an equation of a perpendicular line but with the same y intercept
Open bracket
A linear equation is represented with:
Where
By comparison:
So, the slope of is m
Because the new line is perpendicular to , the relationship between their slopes is:
Where
slope of the first equation
slope of the second equation
Substitute m for in
Hence, the slope of the new equation is:
From the question, we understand that they have the same y intercept.
So, the equation of the new equation is:
