In the figure, if XZ is 10cm, calculate RY in cm
Attached Figure / Diagram
A
10
B
10(1 - \(\frac{1}{\sqrt{3}}\))
C
10(1 - \(\frac{1}{\sqrt{2}}\))
D
10(1 - \(\sqrt{3}\))
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
RY = YZ - RZ
= 10 tan 45 - 10 tan 30
= 10(1 - \(\frac{1}{\sqrt{3}}\))
