The complete question in the attached figure

we know that
If two chords intersect in the interior of a circle, then the product of the lengths of the segments of one chord is equal to the product of the lengths of the segments of the other chord (Segments of Chords Theorem)

therefore

AB*BC=DB*BE
AB=x
BC=x
DB=62
BE=250-62---------> BE=188 ft

so
x*x=62*188----------> x²=11656--------> x=√11656--------> x=107.96 ft

the answer is x=107.96 ft

The elevator of a high-rise office building provides access to all floors. if each floor is 5 meters high and the elevator trave
nadya68 [22]
Height of each floor = 5 meters
time to travel from the first floor to 68th floor = ?
Speed of elevator = 7.5m/s
While an elevator travels from 1st floor to 68th floor, we will multiply the height of floor with 67 to get the distance covered by the elevator form 1st floor to 68th floor, the height of 68th floor will not be counted in the distance because an elevator reaches the 68th floor not covered the height of that floor.
Distance = 5 x 67 = 335m
Now calculate the time by using the formula;
time = distance / speed
= 335m / 7.5m/s
= 44.667 seconds
Thus, an elevator will take 44.667 seconds to reach 68th floor.
