Answer:
The answer is 2 1/2 or in mixed form 5/2
Hope I helped :)
<span>Using: a^2 + b^2 = c^2 (pythagoras theorem)
where 'a' and 'b' are the legs of a right triangle, c is the hypotenuse
</span><span>compare the triangle I just drew to the triangle you have for your problem
</span><span>you'll see that a = unknown b = 18 c = 36
</span><span>a=18sqrt3
=31.2</span>
Between 0.5 and 0.6 can be an infinity.
<em><u>ex:</u></em><u /><u><em /></u><em />
0.51
0.52
0.517
0.5169889549.......
0.5999999999..........
etc.
Assuming this is a multiple choice question where the layout got lost:
√-72 = i√2*36 = 6i√2
This is the last answer in the list of options
