Answer 1

Answer:

9.9 cm

Step-by-step explanation:

We can use the Pythagorean theorem to find the length of CY.

a² + b² = c²

CY² + YZ² = CZ²

YZ = XY  since CZ is the perpendicular bisector

YZ = 5

CZ = 7

CY² + 5² = 7²

CY² + 25 = 49

Subtract 25 from each side

CY² = 49 - 25

CY² = 24

Take the square root of each side

√(CY²) = √(24)

CY = 4.898979 cm

CY = 4.9 cm

We want the length of YW.

YW = WC + CY

WC is a radius which is 5 cm

YW = 5 cm + 4.9 cm

YW = 9.9 cm
