answer:

c.

step-by-step explanation:

it is c. because when i worked this out, c is what i got

hello from mrbilldoesmath!

answer:

the length of the remaining side is sqrt (105.79). (approximately   10.29 )

discussion:

this is a right triangle (meaning it has a 90 degree angle) so the pythagorean theorem applies.   this states that

a^2 + b^2 = c^2

where "a" and "b" are the sides of the triangle and "c" is the hypotenuse (longest side). suppose we call the side in the diagram without a length "a". then by pythagoras

a^2 + (3.9)^2 = 11^ 2             =>

a^2 + 15.21   =   121                 => subtract 15.21 from both sides

a^2 = 121 - 15.21 = 105.79     => take the square root of both sides

a = sqrt (105.79)   which is approximately   10.29
