Answer:
Step-by-step explanation:
we want y by itself...sooo
y - 19 = - (x - (-5))
y - 19 = - (x+5)
y - 19 = - x -
y = - x - 3 +19
y = - x + 16
Answer:
x = -2
Step-by-step explanation:
The tangent line has length "x + 8"
The secant line has length "x + 6 + 5", where
5 is the inner part
x + 6 is the outer part
Now,
the secant-tangent theorem tells us that square of the tangent line is equal to the outer segment of secant line multiplied by length of whole secant line.
So, we can say:
We can solve for x shown below:
The value of x is -2
