For this case what you should do is use the following trigonometric relationship
senx = (1200) / (2400)
senx = 0.5
Clearing the angle we have
x = ASIN (0.5)
x = 30
Answer:
The angle of elevation from the base to the top of the mountain is 30 °
Well 200 beats per second is 12,000 beats a minute times 3 for 3 minutes is 36,000 beats every three minutes

Step-by-step explanation:
we have

Adds
both sides


square root both sides

therefore
<u>the answer is</u>
the resulting equation is 
3x(x^2+4)
3x(x^2)+3x(4)
=3x^3+12x
