Question

In the fig. AB=AC and angle BAC= 90° then prove that L||M . Also find the value of x and y ​

Answer 1

Step-by-step explanation:

We have,

         AB=1 m=100 cm, AC=75 cm and BD=125 cm.

In △BAC and △BDA, we have

        ∠BAC=∠BDA         [Each equal to 90∘]

and,  ∠B =∠B

So, by AA-criterion of similarity, we have

      △BAC∼△BDA

⇒   BDBA=ADAC

⇒  125100=AD75

⇒  AD=100125×75cm=93.75cm
