Question

3. Determine the length of , given by x in the figure. Give your answer to two decimal places.You may use the Desmos scientific calculator:

Answer 1

`\begin{gathered} x=BA-DA \\ DA=3,\text{ because this length is the radius of the circle} \\ BA=√(6^2+3^2) \\ BA=√(45) \\ BA=6.71 \\ Hence \\ x=6.71-3 \\ x=3.71 \\ The\text{ length of BD is 3.71} \end{gathered}`
