Question 877716: What is b if a is 11 and c is the square root of 137

You can put this solution on YOUR website!
your equation is:
c^2 = a^2 + b^2
c^2 is equal to 137
b^2 is equal to 11^2 = 121
c^2 = a^2 + b^2 becomes:
137 = a^2 + 121
a^2 = 137 - 121 = 16
a = 4
you have:
a = 4
b = 11
c = sqrt(137)
a^2 + b^2 = c^2 becomes:
4^2 + 11^2 = 137 which becomes:
16 + 121 = 137 which becomes:
137 = 137
solution is confirmed as good.
