Angles Formed from Two Tangents Two Secants and a Tangent and a Secant

The measure of an angle formed by two secant lines that intersect inside a circle is _______ the sum of the measures of the intercepted arcs.

Find the measure of arc WZ. Which is incorrect?

• 107 = ½(74 + WZ)

• 107 = ½(74) + ½WZ

• 2(107 - 37) = WZ

• WZ = 140

• None of these

What is 𝙢∠𝘼𝘽𝘿? Which step is incorrect?

• Find arc CA: 360 - (139 +151)

• arc CA = 70

• 𝙢∠𝘼𝘽𝘿 = ½( AD - AC)

• 𝙢∠𝘼𝘽𝘿 = ½( AC - AD)

• 𝙢∠𝘼𝘽𝘿 = 40.5

What is the measure of arc LM? Which step is incorrect?

• ∠LJM = ½(LM - KN)

• 34 = ½(6x + 6 - (3x - 5))

• 34 = ½ (3x + 1)

• x = 19

• arc LM = 6 (19) + 6 = 120
