Answer:
Explanation:
in a right triangle a^2+b^2=c^2,
where a and b are the legs
where c is the hypothenuse
9^2= b^2+3^2
81-9=b^2
b^2=72
b=8.48
Givens
a = ?
b = 3
c = 9
Formula
a^2 + b^2 = c^2
Solution
a^2 + 3^2 = 9^2
a^2 + 9 = 81
a^2 = 81 - 9
a^2 = 72
Now the tricky part. Are you required to give the exact answer which is
a = √72 = 6√2
or should you give
a = √72 = 8.49
