Question

pls solve this question with solution??​

Answer 1

Answer:

by Pythagoras therom

BDsq=BCsq+CDsq

x=12sq+9sq

x=144+81

x=225

x=15sq

Answer 2

In the given figure ,

∠ABC = ∠BDC=90°

In △BDC

BC²=BD²+CD²[pythagoras theorem]

BC²=18²+24²

BC=30

In △ABC

AC²=AB²+BC²

50²=AB²+30²

AB²=1600

AB=40

now,2 tan n - sin y

=2[BC/AB]-[BD/BC]

= 60/40 - 18/30

= 3/2 - 3/5

=9/10 ans

hope this will help you......
