What’s the value of x? :/
Answers
Answer:
[tex] x = 27 [/tex]
Step-by-step explanation:
According to congruent chords and arcs theorem, if [tex] \overline{XY} \cong \overline{ZY} [/tex] then [tex] \arc{XY} \cong \arc{ZY} [/tex].
This means that [tex] \arc{XY} = \arc{ZY} = (6x - 20) degrees [/tex]
Thus:
[tex] \arc{XY} + \arc{ZY} + \arc{ZX} = 360 [/tex] (full circle = 360°)
[tex] \arc{XY} = (6x - 20) [/tex]
[tex] \arc{ZY} = (6x - 20) [/tex]
[tex] \arc{ZX} = 76 [/tex]
Plug in the values into the equation
[tex] (6x - 20) + (6x - 20) + 76 = 360 [/tex]
[tex] 6x - 20 + 6x - 20 + 76 = 360 [/tex]
Add like terms
[tex] 12x + 36 = 360 [/tex]
Subtract 36 on both sides
[tex] 12x = 360 - 36 [/tex]
[tex] 12x = 324 [/tex]
Divide both sides by 12
[tex] x = 27 [/tex]
