Hint: the angles that the tangents make with the radii are both 90 degrees
jaybear97
  • jaybear97

or would i do 130-90
welshfella
  • welshfella
No - use the fact that the total value of angles in a 4 sided polygon = 360 degrres

would it be 50?
welshfella
  • welshfella
360 - 130 -90-90 = 360 - 310 = 50 degrees Right

using pythagorus theorem (AB)^2 + (CB)^2 = (AC)^2 x^2 + 3^2 = 7^2 x^2 +9=49 x^2 = 40 x=sqrt(40) = 6.32 rounding 6.32 to nearest tenth we have 6.3 as the answer

I'd just like point out that @imqwerty got that one wrong. It would be x^2+3^2=10^2
jaybear97
  • jaybear97
so what would i do for that on then?
imqwerty
  • imqwerty
sorry i took CA as 7

You'd just solve it for x.
jaybear97
  • jaybear97
would i do 100-9 to get x?
imqwerty
  • imqwerty
(100-9)^(1/2)
