X =(-8+√464)/-8=1-1/2√<span> 29 </span><span>= -1.693</span>
Answer:
ok
Step-by-step explanation:
Answer with Step-by-step explanation:
Let F be a field .Suppose
and 
We have to prove that a has unique multiplicative inverse.
Suppose a has two inverses b and c
Then,
where 1 =Multiplicative identity

(cancel a on both sides)
Hence, a has unique multiplicative inverse.
The measure of the other side of a quadrilateral is
cm.
In the given quadrilateral one side is unknown we need to find the unknown side.
By dividing the given quadrilateral into a rectangle and a triangle we can find the other side.
<h3>What is Pythagoras theorem?</h3>
The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides. That is,
.
Now, 
⇒
Therefore, the measure of the other side of a quadrilateral is
cm.
