Answer:
125.5
Step-by-step explanation:
[tex] {120}^{2} + {40}^{2} = {c}^{2} [/tex]
Slove for 120 squared and 40 squared
[tex]14400 + 1600 = {c}^{2} [/tex]
Now add them together
[tex]16000 = {c}^{2} [/tex]
Square root them
[tex] \sqrt{16000 = } \sqrt{ {c}^{2} } [/tex]
[tex]126.4911064 = c[/tex]
Round to the nearest tenth
[tex]126.5 = c[/tex]
