Answer:
x=7
Step-by-step explanation:
First find the slope
Slope formula: (y2-y1)/(x2-x1)
(-4-(-6))/(-2-2) = 2/-4 = -1/2
Slope intercept formula: y = mx + b
Y = -1/2x + b (solve for b)
Plug in any point
-6 = -1/2(2) + b
-6 = -1 + b, b = -5
Solution: y = -1/2x - 5
a. A' means the complement with respect to Z? If so, then
To know A' you need to write all the elements in Z that are not in A.

b. All the subsets of B, is knowed as P(B),

c.
(Add to A the elements of B, or equivalently add to B the elements of A)
d.
express informally speaking the elements that have in common, but there is no element in common, so

The angle is 85 degrees definately
Step-by-step explanation:
<h2>ANSWER:-</h2>
We know that:-
Angle sum property if Triangles tells us that sum of angles of a triangle is equal to 180°.
So, First, we will find the third inner angle.


Now, let us find x.



So, 31° is the answer. (c)
