<u>Given</u>:
The given circle with center at C. The lines AB and AD are tangents to the circle C.
The length of AB is (3x + 10)
The length of AD is (7x - 6)
We need to determine the value of x.
<u>Value of x:</u>
Since, we know the property of tangent that, "if two tangents from the same exterior point are tangent to a circle, then they are congruent".
We shall determine the value of x using the above property.
Thus, we have;
AB = AD
Substituting the values, we get;

Subtracting both sides of the equation by 7x, we get;

Subtracting both sides of the equation by 10, we get;

Dividing both sides of the equation by -4, we get;

Thus, the value of x is 4.
The speaker is the encoder. That is the correct answer B.
Answer:
Good ( 660- 749)
Step-by-step explanation:
Because of this fact:
726 > 660 and 726 < 749
So his credit rating is considered as Good ( 660- 749)
Have a good day
The correct answer is 18 hope that helped♥
Since x=8/3 is a vertical line,the slope is undefined,
