Question

Determine the value of x Round results to an appropriate number of significant digits

Answer 1

Given

Find

The value of x.

Step-by-step explanation

length of AB = 22 - 3 = 19

using the trignometric ratios , we have

`\begin{gathered} \sin13\degree=(BD)/(AB) \\ \sin13\degree=((x)/(2))/(19) \\ \sin13\degree*38=x \\ 8.548=x \end{gathered}`

Final Answer

Therefore , the length of x is 8.548
