Question

Find the value of x, step by step.​

Answer 1

Answer:

6

Step-by-step explanation:

ab line is perpendicular bisector of chord cd as it passes through center of circle

in ∆adb,

<aod=90=<aoc

<ado =30

<dao=180-(90+30)

=180-120

=60

in∆abc &∆adb

ab is common line

<aod=90=<aoc

od=oc

so ∆abc &∆adb are congruent ∆.

so <dao=x=60
