Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.
or
using a^2 - b^2 =(a+b)(a-b)
= sin(2x+x)sin(2x-x)
= sin 3x sin x
Answer:
Step-by-step explanation:
d = r * t Divide both sides by t
r = d / t
d = distance = 2.25 km
t = time = 3 3/4 minutes = 3.75 minutes
r = 2.25 / 3.75
r = 0.6 km / minute
r = 3/5 km / minute

The answer to this is 50 minutes. by then the runner has gone 11 miles in an hour and 50min and the cyclist has gone 11 miles also
Sphere = 4/3 πr^3
4/3 π (3^3) = 36π = 36*3.14 = 113.04 ft^3
