This is very easy!! I have attached a picture I have drawn if you are a visual learner... well, everything else like computations is here.
.
This is the PYTHAGOREAN THEOREM!!
.
If you don't know, it says that the lengths of the legs squared added together all equal the hypotenuse squared in a right triangle!!
.
And if you want to know why the "triangle" has a right angle... well, are towers slanted? I mean, other than the Leaning Tower of Pizza. I mean Pisa.
.
So... we plug it in!!
.
Formula: a^2 + b^2 = c^2.
.
Plug it in: 11^2+ 61^2 = c^2
.
c^2 = 3842.
.
So now what?
.
SQUARE ROOT OF EVERYTHING!!
.
c = <span>√3842.
.
So? c = approximately 61.984.
.
Hope I helped!!</span>
