[tex] c^{2} [/tex] = 144
c = ±[tex] \sqrt{144} [/tex]
c = ±12
c = ±[tex] \sqrt{144} [/tex]
c = ±12
Simplify. Combine like terms
62 + 82 = 144
c² = 144
Isolate the c. Note the equal sign. What you do to one side, you do to the other.
Root both sides
c² = 144
√c² = √144
c = √144
c = 12
12 is your answer for c
hope this helps
