Answer:
The value of x = 4.1 cm
Explanation:
From the figure we can see a circle, with chord 15.6 cm
A right angled triangle with hypotenuse 8.8 cm
To find the value of x
By using Pythagorean theorem,
Base² + Height² = Hypotenuse²
Here Base = x, Height = 15.6/2 = 7.8 cm and Hypotenuse = 8.8 cm
x² + 7.8² = 8.8²
x² = 8.8² - 7.8²
= 77.4 - 60.84
= 16.56
x = √16.56 = 4.07 ≈ 4.1 cm
Therefore the value of x = 4.1 cm
