Answer:

152°

Explanation:

Intercepted arc is going to be two times the inscribed angle. We can see that angle A is subtended by arc BCD. (See attached picture.)

Step 1: Find angle A.

Angles in quadrilateral add up to 360°.

m∠A + m∠B + m∠C + m∠D = 360°

m∠A + 120° + 104° + 60° = 360°

m∠A + 284° = 360°

m∠A = 76°

Step 2: Find the measure of arc BCD.

Intercepted arc is going to be two times the inscribed angle.

measure of arc BCD = 2 × m∠A = 2 × 76° = 152°
