Answer:
B. 6
Detailed explanation:
Alright, so using the Pythagorean theorem,
in this case, we have the "c" and "b" of the triangle. Therefor, we are looking for "a"
so, to solve the problem, simply begin by substituting what you already have:
Now that this is substituted, The next step is to go ahead and find the values after solving the exponents:
Now, we need to find the value of "a".
In this case, we are provided with 4 options and one of them has to be correct.
If "a"=12 then "a squared" would equal 144.
the statement 100=144+64 is incorrect.
If "a"=6 then "a squared" would be 36.
The statement 100=36+64 is correct.
If "a"=36 the "a squared" would be 1296.
The statement 100=1296+64 is incorrect.
If "a"=18, then "a squared" would be 324.
The statement 100=324+64 is incorrect.
Therefor, the answer is B.6
Hope this helps ^-^
