Step-by-step explanation:
Triangle XYZ is isosceles.
Since Angle Y = 90°, Angle Z = (180° - 90°)/2 = 45°.
The length of AB is 25 units
<h3>How to determine the length AB?</h3>
The given parameters are
AC = 15 cm
BC = 20 cm
The triangle is right -angled at C.
So, we have:
AB^2 = AC^2 + BC^2
This gives
AB^2 = 15^2 + 20^2
Evaluate
AB^2 = 625
Take the square roots
AB = 25
Hence, the length of AB is 25 units

Answer:
29
Step-by-step explanation:
From the point where the chords cross, the product of lengths to the circle intercepts is the same for both chords:
LB·LD = LC·LE
10·18 = 9·LE
LE = 180/9 = 20
The the measure of CE is ...
CE = LC +LE = 9 + 20
CE = 29
