Answer:
<u><em>The value of x is 2.6</em></u>
Step-by-step explanation:
<em>Use pythagorean theorem</em>
a^2+b^2=c^2
<em>Then substitute</em>
1^2+2.4^2=c^2
<em>Then evaluate</em>
1+5.76=c^2
<em>Add</em>
c^2=6.76
<em>Isolate c by finding the sqrt of 6.76</em>
c=2.6
n! is called a factorial.
It would look something like this: n! = 1·2·3·...·n
An example:
5! = 1·2·3·4·5 = 120
Answer is to the question is 20
