X/49 = 21/x
x^2 = 21(49) = 1029
x = √1029 = 32.1
x = 32.1
<span><span>In most statistical models
to represent easy percentages, circle is mostly preferred. It is purposefully
designed or rather allotted for functions that included 100%. A pie chart in
technical terms. Imagine an uneaten cake would
represent a 100%. </span></span>In most case scenarios,
when you eat one slice of the cake. You take a portion that decreases it 100%
or a whole presentation, for instance you took 25% slice of cake, what’s left
will be 75% and then when you put back again, the 25% slice will present the
whole 100%. In words, 25% slice of a cake you take, what’s left will just a
portion 75% and unless you put it back it will be whole again.
In the given question, there are several information's of immense importance and they can be used to find the necessary answers. It is already given that John and Andrew have 3.40 pound together. It is also given that John has 1.20 pound more than Andrew. It is also assumed that John has"u" pound and Andrew has "v" pounds.
Then we can write the two equations as
u + v = 3.40
u = v + 1.20
To find the values of u and v, we can replace the u in the first equation with the value of u in the second equation. Then
u + v = 3.40
(v + 1.20) + v = 3.40
2v + 1.20 = 3.40
2v = 3.40 - 1.20
2v = 2.2
v = 2.2/2
= 1.1
Now we replace the value of v in the first equation to find the value of u.
u + v = 3.40
u + 1.1 = 3.40
u = 3.40 - 1.1
u = 2.3
Step-by-step explanation:

Hence, base = 2 units and hypotenuse = 3 units.





Now, we know that :


Therefore, the required answer is 3/√5.
