Step-by-step explanation:
Answer:
p = 30
Step-by-step explanation:
EFGH is a cyclic quadrilateral ( all vertices lie on a circle )
The opposite angles of a cyclic quadrilateral are supplementary, thus
p + 5p = 180
6p = 180 ( divide both sides by 6 )
p = 30
So times $64.80 by 2.5. You minus 20 from that, so that the RacerZ is $142. You take that $142 and times that by 1.09. You get 154.78. Therefore;
Speedmonster- 64.80
RacerZ- 142
Swiftee-154.78
Hope this helps. :)
