Answer:
x = 4.1 cm
Step-by-step explanation:
The chord is divided into two equal parts. A right angle is formed, therefore, to find x, apply pythagorean theorem.
c² = a² + b²
Where,
c = 8.8 cm
a = x
b = 15.6/2 = 7.8 cm
Plug in the values
8.8² = x² + 7.8²
8.8² - 7.8² = x²
16.6 = x²
√16.6 = x
x = 4.1 (to nearest tenth)
