Answer:
152°
Step-by-step 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°

Answer: B. 1/2(y - 116) = 64
Step-by-step explanation:
Since, we know that,
The angle formed by two tangent =
=
Here, Major arc = y°
Minor arc = 116°
And, Angle made by two tangents YX and YZ,
( because,
)
⇒
Which is the required equation to find y, the measure of XWZ.
Thus, Option B is correct.
