In order to derive the base of a triangle from its area, you need its height as well.
In fact, if we solve the area formula for the base, we have

So, the base length would be

where h is the height relative to the base you're interested in.
Answer: FIRST OPTION
Step-by-step explanation:
To solve this problem you must apply the Intersecting Secant-Tangent Theorem. By definition, when a secant line and a tangent lline and a secant segment are drawn to a circle from an exterior point:

The total measure of the secant shown is:

If the radius is 7, then the diameter is:

Therefore:

You also know that:

Keeping the above on mind, you can substitute values and solve for x:

Answer:
32.1. It has the least values in the decimal place. Overall, it's 31.00, but the least decimal value is 32.1
