Answer:
x=40 degrees
Step-by-step explanation:
there is 180 degrees in half a circle,and 180-100=80
and because there are 2 x values on either side you divide that 80 by 2 which gives you 40.
The value would be 28,000*(1-0.0725)*(1-0.0725)*(1-0.0725)*(1-0.0725)*(1-0.0725)
which is 28,000*0,9275

which equals 28,000*0.6863=$19,219
Answer:
x=0, y=3
x=5, y= 2
Step-by-step explanation:
This should help you here are the steps of your problem :)
2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)
2*(1/2)*r+2*r-(9*(1/10))+1 = 0
2*(1/2)*r+2*r-9/10+1 = 0
3*r+1/10 = 0 // - 1/10
3*r = -1/10 // : 3
r = -1/10/3
r = -1/30
r = -1/30
So your answer would be 1/30
