Answer:
The Length of JM is 20.
Step-by-step explanation:
Given,
JKLM is a kite in which JL and KM are the diagonals that intersect at point A.
Length of AK = 9
Length of JK = 15
Length of AM = 16
Solution,
Since JKLM is a kite. And JL and KM are the diagonals.
And we know that the diagonals of a kite perpendicularly bisects each other.
So, JL ⊥ KM.
Therefore ΔJAK is aright angled triangle.
Now according to Pythagoras Theorem which states that;
"The square of the hypotenuse is equal to the sum of the square of base and square of perpendicular".

On putting the values, we get;

On taking square root onboth side, we get;

Again By Pythagoras Theorem,

On putting the values, we get;

On taking square root onboth side, we get;

Hence The Length of JM is 20.
This should be the correct answer,
4.5×10^9x + 0.00045x
Also, some good free calculators that can help with problems like this would be c y m a t h and m a t h w a y .
The Y^2 because 4 to the power of 2 would give you 4x4 which gives you 16
Y=-4x+6 x=1
y=-4(1)+6
y=-4+6
y=2

It will take approximately 13 seconds.
