We are given the following:
AB = 4800 miles
AO = 4000 miles
There is also a rule that states that a line tangent to a circle, will be perpendicular to the radius of the circle at the point of tangency. Therefore, triangle BAO is a right triangle.
We use Pythagorean theorem to solve for the hypotenuse BO.
BO = √(AO²+AB²) = √(4000²+4800²) = 6248 miles
But the problem asks for the length of BC. Since we know that OC is a radius of the circle, then:
BC = 6248 - 4000 = 2,248 miles.
The answer is C.
In order to find the value first multiply both sides by 100 to simplify the equation:
0.05w*100=15*100
5w=1500
Next, divide both sides of the equation by 5:
5w/5=1500/5
w=300
The final solution is w=300!
