If y = 55 cm and w = 73 cm, what is the length of x?
A. 18 cm
B. 91 cm
C. 46 cm
D. 48 cm
To find the length of x, we have to use Pythagoras theorem.
According to Pythagoras theorem:
x^2 = w^2 - y^2
x^2 = 73^2 - 55^2
x^2 = 5329 - 3025
x^2 = 2304
x = √2304
x = 48 cm
Therefore, the length of x is 48 cm.
The answer is D. 48 cm
