Question

Find the unit measure of ADI need help with this

Answer 1

From properties of lines inscribed in circles we will have that:

`\begin{gathered} AD+DB=AB:AD=DB \\ \\ \Rightarrow2AD=AB\Rightarrow AD=(AB)/(2) \\ \\ \Rightarrow AD=(60)/(2)\Rightarrow AD=30 \end{gathered}`

So, the measure of AD is 30 units.
