Hello!
I believe the answer is C.
I hope it helps!
Using Pythagoras Theorem,
(b is the length of the ladder from the ground)
11x11=6x6+(b^2)
121-36=(b^2)
85=(b^2)
b= 9.219544457292887
b is approximately 9.2
The answer is 62,442,656
scientific notation its 6.2442656 * 10 to the 7th power
word form its 62 million 442 thousand 656
I have worked it out the answer equals 2
