Answer: A) 22.62
Step-by-step explanation:
[tex]\sin b=\dfrac{opposite}{hypotenuse}=\dfrac{20}{52}\\\\\\b=\sin^{-1}\bigg(\dfrac{5}{13}\bigg)\\\\\\\large\boxed{b=22.62^o}[/tex]

The value of b is 22.62.
Given that,
- If segment FD = 20 units and segment DE = 52 units
calculation:
[tex]sin b = opposite \div hypothesis\\\\= 20 \div 52\\\\= sin^{-1} (5 \div 13)\\\\= 22.62 ^{\circ}[/tex]
