Answer:
x = ± 6
Step-by-step explanation:
To find x in an equation, isolate it. Whatever you do to one side, do to the other.
In this case, we need to find the square root of both sides in order to have
become
and find the variable's value:

The square root of 36 can be both -6 and 6. (Remember that when finding the square root of a positive number, it will have a negative and positive outcome.) So, x = -6 and 6.
Answer:

Step-by-step explanation:
Answer: The value of x is 22 units.
Step-by-step explanation:
Since we have given that
△FSB∼△ZDR
So, By Similarity theorem, the ratio of corresponding sides must be equal.
So, it becomes

Hence, the value of x is 22 units.
