Hello from MrBillDoesMath!
Answer:
10.2
Discussion:
Let the length of the missing side = "s" Applying the Pythagorean theorem to this right triangle gives:
4^2 + s^2 = 11^2 =>
16 + s^2 = 121 => ( 4*4 = 16, 11*11 = 121)
16 - 16 + s^2 = 121 - 16 => (subtract 16 from both sides)
s^2 = 105 =>
x = sqrt (105)
which is approximately 10.2
