and putting the values of the angles , base and perpendicular
solving
As
put in the above
a = 4 × 3
a = 12 units

Find the value of the constant of proportionality in each table
Table A
For ------>
For ------>
This table has different values of k
therefore
the table A does not represent a proportional relationship
Table B
For ------>
For ------>
For ------>
This table has different values of k
therefore
the table B does not represent a proportional relationship
Table C

For ------>
For ------>
For ------>
This table has the same value of k
therefore
the table C represent a proportional relationship
Table D
For ------>
For ------>
For ------>
For ------>
This table has different values of k
therefore
the table D does not represent a proportional relationship
