Step 1: Recall angle theorem/properties of inscribed quadrilaterals in circle.

Step 2: Note down given values and examine the figure

Step 3: Identify the suitable theorem/property for the given question.

EXAMPLE:  Opposite angles in an inscribed quadrilateral

are supplementary.

[math] \angle L + \angle J = 180\degree

Step 4: Use the theorem/property to find the unknown value.

EXAMPLE: From triangle ABC

\angle L+\angle J\ =180\degree

107\degree+\angle L=180

\angle L=180\degree-107\degree

\angle L=73\degree
