I got X = 6
If you replace x for 6 you should get 216
6^3 = 216
( yx + 4x - 5 )( y + 1 )

Angle A should be equal to 47
Answer:
A
Step-by-step explanation:
They are basically wanting the value of x.
These are 2 secant lines drawn. Secant Line is a line that intersects the circle at 2 points.
To solve this, we have to use secant-secant theorem.
Secant-Secant Power Theorem tells us that if 2 secant lines are drawn from external point (here, E) to a circle, then, product of measure of one secant's external part and total secant is equal to other secants external part and whole secant.
In algebra, that is:

Let's multiply and find the value of x:

Hence, the correct answer choice is A
