Answer:
(3, 4).
Step-by-step explanation:
The x coordinate stays the same but the y coordinate becomes 7 - 3 = 4.
Lol I was looking for help for this question but I couldn't find it so I had to figure it out my self and the answer is 40
A = L^2
A = L^2 = 2^2 + 4^2 (Pythagorean’s theorem)
A = L^2 = 20
Therefore the area of the square is 20 units square.
Ordered pair is 
<u>Step-by-step explanation:</u>
We have the following inequalities:
and 
. In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !
and , 
which implies:
⇒
⇒
⇒ 
putting value of x in both inequalities we get,
and
and 
and 
Hence at x = 
and y = 
above inequalities are satisfied. ∴ Ordered pair is
x = 100°
In a parallelogram all the interior angles must add up to 360°
Opposite angles of a parallelogram are equal
360° = x + x + 80° + 80°
360° = 2x + 160°
2x = 200°
x = 100°
Alternatively:
x and 80° are corresponding angles because they are on the same line that crosses two parallel lines. Corresponding angles are complementary and add up to 180°.
180° = x + 80°
x = 100°
