The TV is 27 inches tall.
Step-by-step explanation:
Given,
The diagonal length of the TV = 45 in
The width of the TV = 36 in
To find the length the the TV.
Formula
By Pythagoras theorem,
h²=l²+b², where h be hypotenuse, b be base and l be height.
Now,
Putting, h=45, b= 36 we get,
45²=l²+36²
or, l²= 45²-36²
or, l²= 729
or, l = √729
or, l = 27
Hence,
The TV is 27 in tall.
