Answer:
352 ft²
Step-by-step explanation:
The formula for the area of a trapezoid is 
where 
and 
are the bases of the trapezoid and 
is the height, thus:
This means that the area of the trapezoid is 352 ft².
Answer:
If P = (x,y) then formulas for each trigonometric functions are:
sin x = y/r
cos x = x/r
tan x = y/x
cot x = x/y
sec x = r/x
cosec x = r/y
where r = √(x²+y²).
First find r:
r = √(13²+84²)=√(169+7056)=√7225=85.
Then just substitute:
sin x = 84/85
cos x = 13/85
tan x = 84/13
cot x = 13/84
sec x = 85/13
cosec x = 85/84
