Step by step:
Answer:
Option.B
Step-by-step explanation:
Its because if you add these two angles you get a supplementary angle or 180°
Using this we can form an equation to find the value of x.
(Hope this answer helps :))
(And is this question from Khan Academy?)
Answer:
<h2>x = 3.499 in</h2>
Step-by-step explanation:
In a kite, the diagonals are perpendicular. Hence
is a right angled triangle.

From Pythagoras theorem, since
is a right angled triangle,
.
Area of
= 

From diagram 
∴ 
Answer:
1/3
Step-by-step explanation:
slope is just change in y over change in x
on a graph this can be found by counting the change in units
look at the point at (-3,0)
find the change in y by starting at that point and counting up or down until you reach another point.
the next point (-4,-3) is three units down (change of -3)
now go back to the first point and count left or right until you reach the other point to get change of x
the other point is one unit left (change of -1)
change of y over change of x = -1/-3=1/3
