Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
If a parallelogram then AB = DC and AD = BC
Equating AB = DC, then
3x = x + 4 ( subtract x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Thus
AB = 3x = 3(2) = 6 and DC = x + 4 = 2 + 4 = 6 ⇒ AB = DC
Equating AD and BC, then
2y = y + 2 ( subtract y from both sides )
y = 2
Thus AD = y + 2 = 2 + 2 = 4 and BC = 2y = 2(2) = 4 ⇒ AD = BC
Since opposite sides are congruent then ABCD is a parallelogram
The y-coordinate of the midpoint, M of the segment AB described by; A(-3,3) and B(5,7) is; 5.
<h3>What is the y-coordinate of the point M which is the midpoint of AB, defined by;
A(-3,3) and
B(5,7).</h3>
It follows from the task content that the y-coordinate of the midpoint, M of AB defined by; A(-3,3) and B(5,7) is to be determined.
Hence, it follows from coordinate geometry that the y-coordinate of the midpoint is such that;
y = (y(1) +y(2))/2
y = (3 + 7)/2
y = 5.
Ultimately, the y-coordinate of the midpoint of AB; A(-3,3) and B(5,7) is; y =5.

Answer:
=36.0
Step-by-step explanation:
We use the sine rule to find the missing sides as follows;
Lets find the missing angle C by using the summation of interior angles in a triangle.
C=180-(44+48)
=88°
Then,
a/Sin A=c/Sin C
25/Sin 44=c/Sin 88
c=(25 Sin 88)/Sin 44
c=35.97
The side c=36.0 to the nearest tenth.
