Answer 2

Step-by-step explanation:

(i)

step- :- LBAC=90 °

:. BC square = ABsquare + AC square

:. (21)square + (28)square

:. 441+784

:. 1225

:. BC= 1225 square root

again BCD= 90°,

:. BC square + CD square

= (35)square + (12)square

= 1225+144

= 1369

BD = 1369sqauare root

= 37

:. x = 37ans
