  • sjg13e
i'm also going to assume r = 7.5

there is one information just r.

  • sjg13e
yes, the only known variable is 'r'. but it seems that there's a way to find the numerical value of theta
anonymous
  • anonymous
theta is approximately 60 degree

  • welshfella
you can make an estimate of the angle theta the slope is about 6.6 so find the angle whose tangent is 6.6
welshfella
  • welshfella
that is 81 degrees to the nearest degree

yes, I get height 8.4 and 1.33 to the right so 90 - arctan(1.33/8.4) = 81

  • welshfella
from this you can find the arc length s
welshfella
  • welshfella
using radius of 7.5

thank you! i'll try to find s

@phi i think its 80 cuz i use long method
sjg13e
  • sjg13e
yeah, it's 80!

@dinamix what do you mean by the long method?
