The answer to your question is z =
Step-by-step explanation:
Process
I'll solve this problem using proportions, I hope it helps you
We consider the adjacent side of both triangle
Adjacent side small triangle = x Adjacent side big triangle = 10
Proportion of these sides =
Now, consider the opposite side of both triangles
Opposite side fo small triangle = 2 Opposite side big triangle = x
Proportion =
Now, equal both proportions and solve for x
x² = 20
x =
x = 2
Using Geometric mean
x =
Using the Pythagorean theorem to find z
z² = (√20)² + 2²
z² = 20 + 4
z² = 24
z =
If
realistic limits are imposed on the choices I would go with 1000 ft.
For the angle of elevation I would chose 34°. This because as we
know an angle of elevation is the angle between the observer's’
line of sight and a horizontal line when the observer looks upward.
If
you wanted to find the height of the cliff you would use the
following:
Tan34
= x/1000
x
= tan(34)*1000
x
= 674.51 ft.
