  • Corresponding sides of congruent angles are congruent ...1

∠ABD = ∠CBD ... angle bisector..2

•°• AD = DC ... from 1,2

x + 1 = y + 2

x - y + 1 - 2 = 0

x - y = 1 ...a

And

∠BDA = ∠BDC = 90° ..3

•°• AB = BC ... from 1 and 3

3x + 1 = 5y - 2

3x - 5y = -2 - 1

3x - 5y = -3 ...b

_______________________________________

now eq:-

x - y = 1 ..a

3x - 5y = -3 ..b

multiplying eq (a) by 3

° 3(x - y = 1)

3x - 3y = 3 ...c

  • subtracting equation B from c

3x - 5y = -3

- (3x - 3y = 3)

-2y = 0

y = 0/2

y = 0

  • substituting y = 0 in eq a

° x - 0 = 1

x = 1

The value for x and y is 1 and 0.
