You answer is B because supplementary is 180°
Answer:
A
Step-by-step explanation:
edge
Y = money left over
X = fair ticket
Y = 36.75 - 3x
Check the picture below.
the segment LOJ is a diameter, and therefore the arcLCJ made by that diameter will have a central angle of 180°.
that simply means that the arcLC is 180 - 94, or 86°.
the ∡LJC is an inscribed angle that is intercepting the arcLC, and therefore, by the inscribed angle theorem, it'll be half of arcLC.
