180 degrees= a whole line
180-102=78
So m13 should equal 78°
It is 165 I hope this helps :)
Answer:
42
Step-by-step explanation:
11 - 4 = 7
49 - 7 = 42
The missing coordinates of the parallelogram is (m + h, n).
Solution:
Given shape is a parallelogram.
Construction: Draw a line joining the diagonals.
<em>In parallelogram, diagonals bisect each other.</em>
Solve it using mid-point formula:

Here 


Using this midpoint find the missing coordinate.

Let the missing coordinates by x and y.
Here 



Now equate the x-coordinates and y-coordinates.

Multiply by 2 on both sides of the equation, we get
m + h = x, n = y
x = m + h and y = n
Hence the missing coordinates of the parallelogram is (m + h, n).
