Question

Find the measure of angle $b$.(in degrees)

• A. ${48}^{\circ }$
• B. ${53}^{\circ }$
• C. ${79}^{\circ }$
• D. None of these

Answer 1

The correct option is C ${79}^{\circ }$

The tangent chord theorem state that the angle between a tangent and a chord is equal to the inscribed angle on the opposite side of the chord.

$\therefore \angle b=\angle 79$
