Answer:

x = 4.1 cm

Step-by-step explanation:

To find x, apply pythagorean theorem, which is given as:

c² = b² + a²

Where,

c = 8.8 cm

b = ½(15.6) = 7.8 cm

a = x

Plug in the values

8.8² = 7.8² + x²

77.44 = 60.84 + x²

Subtract both sides by 60.84

77.44 - 60.84 = x²

16.6 = x²

Take the square root of both sides

√16.6 = x

x = 4.07430976

x = 4.1 cm (nearest tenth)
