Problema Solution
Use the Pythagorean theorem to find the missing side.
c= 9, b = 4 find a
Answer provided by our tutors
Assuming a and b are the legs and x is hypotenuse of a right triangle we have:
a^2 + b^2 = c^2 (Pythagorean Theorem)
a^2 = c^2 - b^2
a^2 = 9^2 - 4^2
a^2 = 81 - 16
a^2 = 65
a = 8.06
We ignore the negative solution since the length can only be positive.
