Find the value of x rounded to the nearest tenth the answers are 4,3.8,2.7,2.9

x=4

Step-by-step explanation:

Missing picture is attached.

As we can see in the picture drawn, there are two cord insecting outside the circle.

∴ we will use Intersecting secant theorem.

When two secant lines intersect each other outside a circle then the product of the length of the chord and the length of the part outside the circle are equal.  

Now, using the value in theoram as given in the picture.

⇒

Dividing both side by 6

⇒

∴x= 4

idk

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86
