I really need some help with this, if someone could put in an answer that would be a lot of help!

For the information given, a line segment of 4 inches can be drawn

<h3>How to illustrate the segment?</h3>

For the 'copy', you would measure the line drawn, and duplicate it to the right, measuring it to make sure it is the exact length of the first line.

To bisect the original line segment, measure the line with a ruler or other device, and calculate 1/2 distance from one end, mark it, measure from left end to mark, make sure right section is equal in length.

Draw an angle of  90 degree and label it to avoid confusion. Now use a scale to draw a ray and label the vertex point so we can know  the point where to place compass. Use compass to draw an arc on angle. This angle will help you measure where to put the new point on our new angle.

Similarly draw the same arc  on the new ray. This is the first step in finding the new point. Then, use compass to measure the difference between the two places where the arc meets the angle on angle.

Furthermore, use the measurements from the previous step to draw another arc. This step is to help establish a point where the two arcs meet. Now draw a point where the two arcs met and drew a line through it.

What is the value of the missing angle?a, 720b, 120c, 128d, 138
Zigmanuir [339]
The sum of all the interior angles in a hexagon is 720°, so if you add up all the angles and then take them away from 720, you'll get your answer:
152 + 85 = 237
237 + 85 = 322
322 + 125 = 447
447 + 135 = 582
So 720 - 582 = 138°, which is your answer. I hope this helps!
