Answer:
the correct answer is 8,000ft
Step-by-step explanation:
sin30°=4000ft/h
hsin30°=4000ft
h=4000ft/sin30°
h= 8,000ft

Answer:
<h2>D.
x ≈ 31.3°</h2>
Step-by-step explanation:
The triangle CBV is angled triangle with right angle at ∠VBC.
Since ∠VBC = (3x-4) °
To get the value of x, we will equate the angle ∠VBC to 90°
This results into (3x-4) ° = 90
Simplifying the resulting equation;
3x-4 = 90
Adding 4 to both sides;
3x-4+4 = 90+4
3x = 94
Dividing both sides by 3
3x/3 = 94/3
x = 31.33°
x ≈ 31.3°
