Respuesta :

<y = 1/2(247 - x)

67 = 1/2(247 - x)

or

1/2(247 - x) = 67

Answer is B.

1/2(247 - x) = 67


Answer:

The answer is the option B

[tex]\frac{1}{2}(247\°-x\°)=67\°[/tex]

Step-by-step explanation:

we know that  

The measurement of the outer angle is the semi-difference of the arcs it comprises.

so

[tex]m<y=\frac{1}{2}(arc\ XWZ-arc\ XZ)[/tex]

we have that

[tex]m<y=67\°[/tex]

[tex]arc\ XZ=x\°[/tex]

[tex]arc\ XWZ=247\°[/tex]

substitute the values

[tex]67\°=\frac{1}{2}(247\°-x\°)[/tex]
