Cosec θ = 1.6981
1/sin θ = 1.6981
sin θ = 1 / 1.6981 = 0.5889
θ = arc sin 0.5889 = 36.1 degrees
Mean = Sum of points / Number of points ;
27 = ( 25 + 28 + 36 + 21 + 28 + 15 + 24 + 30 + x ) / 9 ;
243 = 207 + x ;
x = 36 is the number ;
We can ise Pythagorean triplet which is ( 12 , 16 , 20 )
Therefore the answer is 16.
Step-by-step explanation:
Or we can use Pythagoras theorem , stated as ;
( hyp )^2 = ( adj )^2 + ( opp )^2
hyp ( hypotenuse ) = 20
We can assume the adj ( adjacent ) = 12
By substituting the values ,
20^2 = 12^2 + ( adj )^2
400 = 144 + ( adj )^2
400 - 144 = ( adj )^2
256 = ( adj )^2
Take the square root of both sides
✓256 = adj
16 = adj
Therefore the length of the other leg which is the adjacent( adj ) side is 16.
