Answer:
BC = 26
Step-by-step explanation:
Given that:
B is the midpoint of AC
Then AC = AB + BC
AC = 8x - 20 and AB = 3x - 1
Then,
8x - 20 = (3x - 1) + BC
8x - 20 - (3x - 1) = BC
8x - 20 - 3x + 1 = BC
5x - 19 = BC
But AB = BC
5x - 19 = 3x - 1
5x - 3x = - 1 + 19
2x = 18
x = 9
Hence,
Since BC = AB = 3x - 1
3(9) - 1
27 - 1
= 26

Step-by-step explanation:
The missing image is attached.
It is important to remember that a protractor is a measuring instrument that is used to measure angles in degrees.
Then, in order to measure an angle in degrees using a protactor, you can follow these steps:
1. You must place the center point of the protractor on the vertex of the angle.
2. Then, you must line up the base line of the proctactor with one side of the angle.
3. Finally, you can read the angle in degrees.
In this case, you can observe in the image attached that the protractor is placed on the vertex "H" of the angle JHG.
Therefore, based on the explanation shown before, you can identify that the meausre in degrees of the angle JHG is the following:
