4 0

$3i(6+2i) = 18i+6i^2 = 6i(3+i)$ if i is a variable

$3i(6+2i) = 18i+6i^2=18i+6(-1) = -6+18i = 6(-1+3i)$ if i is the imaginary unit defined by i²=-1

Based on the tangent theorem, m∡ADO = 90°.

Based on the angles of intersecting chords theorem, m∡CGF = 1/2(mCF + mDE).

What is the Angles of Intersecting Chords Theorem?

The angles of intersecting chords theorem states that when two chords in a circle intersect, the angle formed inside the circle at the point of intersection has a measure that is half of the sum of the measures of the intercepted arcs that are formed by the angle and its vertical angle.

<h3>What is the Tangent Theorem?</h3>

According to the tangent theorem, if a line is tangent to a circle, the segment forms a right angle at the point of tangency with the radius of the circle.

Since line AB is tangent to circle O at point D, therefore, based on the tangent theorem:

The measures of angle ADO = 90°

Chord CE and DF intersect in the circle, therefore, based on the angles of intersecting chords theorem:

The measure of CGF = 1/2(mCF + mDE).

This is the answer unless the 2/4 is meaning divide the two if thats the case the answer is 48+√2 over 8
