Answer:
x = 14
Step-by-step explanation:
Assume your diagram is like the one below.
The intersecting secant angles theorem states, "When two secants intersect outside a circle, the measure of the angle formed is one-half the difference between the far and the near arcs."
For your diagram, that means
Check:
It checks.
Answer:
C: or
Step-by-step explanation:
To solve the equation we need to factor it
We are looking for two numbers that when multiplied give -12 and when added give -x
This means that when factored, the equation would be
Now we can set each of these equal to 0, which means that at
and
, the equation will equal 0
