Solve for x. Assume that lines which appear tangent are tangent.

NeX [460]

Answer:

x=2

Step-by-step explanation:

The angle formed by two tangents intersecting outside of a circle is half the difference of the intercepted arcs.

This implies that:

$55=\frac{1}{2}(116x+3-(180-55))$

We need to simplify this ad solve for x to get:

$110=(116x+3-125)$

Group the similar terms to get:

$110-3+125=116x$

232=116x

Divide by 116 to get:

x=2

What is the domain of g?

Mrac [35]

Answer:

Solution. The domain of g(x) consists of all real numbers except x = 32, since that input value would cause us to divide by 0. Likewise, the domain of f consists of all real numbers except 1. So we need to exclude from the domain of g(x) that value of x for which g(x) = 1.
