Enter your answer as a decimal in the box

In.

14.  

a^2 + b^2 = c^2

12^2 + 7^2 = c^2

144 + 49 =c^2

193 = c^2

c= 13.89

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
