SOLUTION: The angle of elevation of point Q from point P is given as 40.2°, PQ=26.7m. How high is point Q above the level of point P?

Make a sketch if you need it.


Let x be "How high is point Q above the level of point P", 
i.e. the value under the problem's question.


You have a right-angled triangle.
PQ = 26.7 meters is its hypotenuse;
The angle of elevation of 40.2° is the opposite angle to leg x,
so you can write

    sin(40.2°) = ,

based on the definition of sine. From this equation

    x = 26.7*sin(40.2°).
