<h3>Answer: 65/63</h3>
=================================================
Explanation:
Draw a right triangle in the first quadrant, aka northeast quadrant, as shown in the diagram below.
Cosecant involves the ratio of hypotenuse over opposite. It's the reciprocal of sine
sin(angle) = opposite/hypotenuse
csc(angle) = hypotenuse/opposite
since csc = 1/sin
Use the pythagorean theorem to solve for b in the diagram
a^2+b^2 = c^2
16^2+b^2 = 65^2
256+b^2 = 4225
b^2 = 4225-256
b^2 = 3969
b = sqrt(3969)
b = 63
So this is the adjacent side. The secant ratio involves hypotenuse over adjacent (it's the reciprocal of cosine).
sec(angle) = hypotenuse/adjacent
sec(A) = 65/63
Answer:
The change in elevation is 20,744 ft
Step-by-step explanation:
Let
x -----> the lowest elevation in a region
y -----> the highest elevation in a region
we have that
x=-264 ft
y=+20,480 ft
We know that
To find out the change in elevation from the lowest elevation to the highest elevation, subtract the lowest elevation from the highest elevation (or find the difference in absolute value)
so
y-x
substitute the values
