Answer:
<h2>x = 117°</h2>
Step-by-step explanation:
We know:
The sum of the quadrilateral angles measures 360°.
Therefore we have the equation:

The sum of angles x and D is equal to 360°. Therefore we have the other equation:

From (1) and (2) we have:

80$ because 50 divided by 3 is 16.67 and 80 divided by 5 is 16 so yeah $80
Answer:
ill help u lol im pretty positive its 8
<u>m= -19/1</u>
We need to use the slope equation

We are working with the points,
(17, 2) and (18, -17)
x1 y1 x2 y2

<u>m= -19/1</u>
Answer: PQ = 18
Step-by-step explanation:
You would divide 21/14 to see what the size difference in the triangles is to get 1.5. 1.5x12=18
