Answer:
(±1, -2)
Step-by-step explanation:
The co-vertices are the end points of the minor axis. The center is at (0, -2) and the minor axis is 2 units long, so the co-vertices are ...
(-1, -2) and (1, -2)
Answer:
x = 
Step-by-step explanation:
We know that;
The triangle is isosceles, and the hypotenuse is x, the un-labeled side is 5.
Therefore we can say;
5² + 5² = x²
25 + 25 = x²
50 = x²
= x
We can simplify this further;
= 
= 
Hope this helps!
Answer:
x = negative 1 plus-or-minus StartRoot 17 EndRoot
Step-by-step explanation:
Given:

We need to solve for x.

First we will solve L.H.S
Factorizing the equation we get;

Now Things which are equal to the same thing are also equal to one another. Since


then, according to the law of transitivity,

Now, applying the Square Root Principle we get:

Now Square root and square gets cancelled.

Since a square root has two values, one positive and the other negative.

Hence Final Answer is
.
The sum of the sides of a quadrilateral is equal to 360º.
x= 4th angle measurement
We have the following equation:
90+156+28+x=360
x=360-90-156-28
x=86
Answer: the size of the 4th angle would be 86º.
