Step-by-step explanation:
The calculation of size for a new television is shown below:-
With the help of Pythagoras theorem

where
h indicates hypotenuse which is the diagonal length
b indicates the base which is the length of the horizontal side
p indicates perpendicular which is the TV length of the vertical side.

now, we will put the values into the above formula

Which gives result
= 36.7
or
= 37

Answer with Step-by-step explanation:
Let a and b are two integers.
We have to show that
if 3\a+b then 3\a-b is false.
In order to prove that given statement is false we prove this with the help of example
Suppose we have two integers a=2 and b=4
if 3\2+4
3\6=2
2-4=-2
But 3 does not divide -2.
Therefore, the given statement is false.
Hence, proved.
