Answer:
B
Step-by-step explanation:
According to the given situation,
If X, then Y indicates y depends on X
If Y, then Z indicates Z depends on Y
As per the given situation, Y is true also Z will be true on the other hand there no solution about x b as y depends on X
Therefore as per the above explanation, the correct answer is B and hence the same is to be considered
Answer:
Option B. x = 13
Step-by-step explanation:
In this question, we shall give a separate diagram which will help us to further understand the question.
Please see attached photo for further details.
To find the value of x we shall use the pythagoras theory as illustrated below:
x is the longest side Therefore,
x² = 12² + 5²
x² = 144 + 25
x² = 169
Take the square root of both side
x = √169
x = 13
Therefore, the value of x 13.
