Question

find the value of x????.......
​

Answer 1

Answer:

X=2.25

Step-by-step explanation:

Use Pythagoras theorem in triangle ADB,and find the value of (AD)^2.

Such that, AD^2=16-x^2.           {Equation no. 1}

Now, Again by using Pythagoras theorem in triangle ADC,and find the value of AD^2.

Such that,AD^2= 12x-x^2-11.         {Equation no. 2}

Now, by camparing Eq.1 and Eq.2,

16-x^2=12x-x^2-11

X=9/4=2.25.
