Answer:
x = 4 in
Step-by-step explanation:
Given a tangent and a secant to the circle from an external point, then
The square of the tangent is equal to the product of the secant's external part and the entire secant, that is
x² = 4(4 + 8) = 4 × 12 = 48 ( take the square root of both sides )
x = =
=
×
= 4
← exact value

Definition of mid- segment
It is a segment connecting the midpoints of two sides of a triangle.
It is always parallel to the third side, and the length of the midsegment is half the length of the third side.
As shown in the triangle given below.
As given
DE = 5x and BC = 11x – 15
Thus
15 = 11x - 10x
15 = x
Therefore the value of x is 15 .

Ratio of the outer sector to inner sector
The area of a sector is:
For the inner circle
The sector of the inner circle has the following area
For the whole circle
The sector of the outer sector has the following area
So, the ratio of the outer sector to the inner sector is:
Cancel out common factor
Express as fraction
