Step-by-step explanation:
Hey there!
Given;
Midpoint is (-1,3) and one endppint is; A(4,-1).
Let the coordinates of C be (x,y).
<u>Use</u><u> </u><u>the</u><u> </u><u>midpoint</u><u> </u><u>formula</u><u>.</u>
<u>
</u>
<u>Put</u><u> </u><u>all values</u><u>. </u>
<u>
</u>
Since, they are equal, equating with their corresponding elements we get,

Answer:
Step-by-step explanation:
first, you have to recognize that the two angles will be the same. They are like that b/c of how they are opposites. next , b/c they are the same , set them equal to each other and then solve the equation for x ( isolate x)
29 = 4x -1
29 + 1 = 4x -1 + 1
30 = 4x
30/4 = 4x /4
7.5 = x
now to find ∠DCE just plug in x, but you also can just observe that ∠DCE is going to be 29° b/c the angle opposite of it is also.

Answer:
It will be 2.83 inches long on the drawing
Step-by-step explanation:
The scale we have is;
0.5 in to 3 ft
This;
x in to 17
17 * 0.5 = 3 * x
8.5 = 3x
x = 8.5/3
x = 2.83 inches
