1. Inscribed & Central Relationships

Given circle \(O\), if \(\text{m}\angle ABC = (3x + 10)^\circ\) is an inscribed angle and its intercepted arc \(AC = (8x - 20)^\circ\), calculate the value of \(x\) and the measure of \(\text{minor arc } AC\).

Work Space

\(x = \underline{\hspace{20px}}\)

\(\text{m}AC = \underline{\hspace{20px}}^\circ\)

ID: 102

2. Internal Intersections

Chords \(AB\) and \(CD\) intersect at point \(P\) inside the circle. If \(\text{arc } AC = 110^\circ\) and \(\text{arc } BD = 40^\circ\), find \(\text{m}\angle APC\). If \(\angle APD = (5x + 5)^\circ\), solve for \(x\).

Work Space

\(\text{m}\angle APC = \underline{\hspace{20px}}^\circ\)

\(x = \underline{\hspace{20px}}\)

ID: 103

3. Exterior Convergence

Two secants are drawn from point \(E\) outside the circle. Secant 1 intercepts arcs of \(150^\circ\) (far) and \(60^\circ\) (near). Secant 2 intercepts arcs of \(x^\circ\) (far) and \(40^\circ\) (near). If the angle at point \(E\) is consistent for both secants, find the value of \(x\).

Work Space

Hint: Calculate the angle at point \(E\) using Secant 1 first.

\(x = \underline{\hspace{80px}}\)

4. Chord-Chord Power

In circle \(O\), chord \(XY\) and chord \(ZW\) intersect at \(M\). If \(XM = 6\), \(MY = x + 2\), \(ZM = 4\), and \(MW = 2x + 1\), solve for \(x\) and find the total length of chord \(ZW\).

Work Space

\(x = \underline{\hspace{30px}}\)

\(ZW = \underline{\hspace{30px}}\)

ID: 202

5. Secant-Secant Dynamics

From exterior point \(P\), secant \(PAB\) and secant \(PCD\) are drawn. \(PA = 4\), \(AB = 8\), and \(PD = 16\). Find the length of the internal part of the second secant (\(CD\)).

Work Space

\(CD = \underline{\hspace{60px}}\)

ID: 203

6. Tangent-Secant Stress Test

A tangent segment \(PT\) has a length of \(x+2\). A secant segment \(PAB\) from the same point \(P\) has an external part \(PA = x-1\) and an internal part \(AB = x+7\). Solve for \(x\). (Round to nearest hundredth if necessary).

Work Space

CRITICAL WARNING

Remember: (Tangent)² = (Whole Secant) × (External Part).

\(x = \underline{\hspace{80px}}\)

Module 3.0: System Synthesis

Final Diagnostic Challenge

In the diagram of circle \(O\) (not pictured), tangent \(PA\) and secant \(PBC\) are drawn from point \(P\). The measure of arc \(AC\) is twice the measure of arc \(AB\). If \(\text{m}\angle P = 30^\circ\), find the measure of all three arcs of the circle: \(AB\), \(BC\), and \(CA\).

Final Outputs

\(\text{m}AB = \) \(\underline{\hspace{80px}}^\circ\)

\(\text{m}BC = \) \(\underline{\hspace{80px}}^\circ\)

\(\text{m}CA = \) \(\underline{\hspace{80px}}^\circ\)
