You have run aground. Your boat draws 6 feet when upright.
You think you can heel your boat 10 degrees by kedging with an anchor.
How much is is this going to reduce your draft?

Now, your toerail is underwater at 30 degrees of heel.
What will your draft be now?

6 sin 80 is about 5ft 10.8 in (heel 10 deg).
6 sin 60 is about 5. ft 2.4 in. heel 30 deg)
6 sin45 is about 4 ft 3 in (heel 45deg)
