Question

Find the indicated length. Assume lines that appear to be tangent are tangent. Round tothe nearest tenth if necessary.6?6.4

Answer 1

Given

Find

Length of AC

Explanation

as we have given right angle triangle

by pythagoras theorem ,

$AC^2=AB^2+BC^2$

as

AB = 6 + 6 = 12

so ,

$\begin{gathered} AC^2=12^2+(6.4)^2 \\ AC^2=144+40.96 \\ AC^2=184.96 \\ AC=\sqrt{184.96} \\ AC=13.6 \end{gathered}$

Final Answer

Hence , the length of AC is 13.6 . So , the correct option is 4
