Answer:
Right Triangle
Step-by-step explanation:
BC is tangent to circle O, and since radius OB is perpendicular to this tangent, then the triangle must have a right angles in it, making it a right triangle.
The triangle could also be scalene, but that is not for sure, meaning it is primarily a right triangle.

Step-by-step explanation:
Answer: C)46 ft
Step-by-step explanation:
We know that the circumference of a circle can be calculated with this formula:

Where "r" is the radius of the circle.
Since John is putting a fence around his garden that is shaped like a half circle and a rectangle, then we can find how much fencing he needs by making this addition:

Where "l" is the lenght of the rectangle and "w" is the width of the rectangle.
Since we know that the radius of the circle is half its diameter, we can find "r". This is:

Then, substituting values (and using
), we get:

If secant of theta =
<span>
<span>
<span>
1.0416666667
</span>
</span>
</span>
then
theta = 16.26 Degrees
cotangent of theta = 3.4286
