The picture in the attached figure
we know that
If a tangent segment and a secant segment are drawn to a <span>circle </span><span>from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment
</span>so
DC²=BC*CA-----> CA=DC²/BC
DC=25
BC=14
CA=25²/14-----> CA=44.64
CA=BC+BA----> BA=CA-BC----> BA=44.64-14----> BA=30.64
BA is the diameter
hence
<span>the length of diameter BA is 30.64----> round to the nearest tenth---> 30.6
</span>
the answer is<span>
the length of diameter BA is 30.6</span>

Answer:
Width of the house is 15.25 feet.
Step-by-step explanation:
Jason ran around his house = 3 times
In this run he covered total distance = 274.5 feet
Perimeter of the house = 2(length + width)
= 2(30.5 + width)
Perimeter of the house is the distance covered by Jason in one round.
So, distance covered in 3 rounds = 3[2(30.5 + width)]
274.5 = 6(30.5 + width)
274.5 = 6(30.5 + width)
45.75 = 30.5 + width
width = 45.75 - 30.5
width = 15.25 feet
Therefore, width of the house is 15.25 feet.
