A) 5 cm
B) 10 cm
C) \[5\sqrt{2}\,\,cm\]
D) 2.5 cm
Correct Answer: C
Solution :
[c] \[\Delta ABC\] Is an isocoles triangle. Therefore, AC=BC=5 cm Now, \[A{{B}^{2}}=A{{C}^{2}}+B{{C}^{2}}\] \[A{{B}^{2}}={{5}^{2}}+{{5}^{2}}\Rightarrow \sqrt{25+25}=5\sqrt{2}\,\,cm\]You need to login to perform this action.
