Question

pls give fast n right answer or jise aata vuhi do​

Answer 1

In ΔABC,∠ABD=∠DBC

AD/DC = AB/CB (By angle bisector theorem)

=> (x-2) / (x+2) = x / (x+5)

=> (x-2) × (x+5) = x(x+2) { By cross multiplication}

=> x(x+5) -2(x+5) = x²+2x

=> x² + 5x - 2x - 10 = x²+2x

=> x²+3x−10 = x²+2x

=> 3x−2x = 10

=> x = 10
