Answer:
the answer for this question is
10-1.125=71/8 or 8.875
= 9
The choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units
<h3>How to determine the
choices that are correct when determining the
distance between −56 and 69?</h3>
The endpoints are given as
−56 and 69
The distance between the endpoints is calculated using
Distance = |Difference between endpoints|
So, we have:
Distance = |-56 - 69|
Evaluate
Distance = 125
Hence, the choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units

<h3>
Answer: C) 136 degrees</h3>
The known acute angle of the triangle is 46 degrees, so the unknown acute angle of that triangle is 90-46 = 44 degrees. In other words, the two acute angles of any right triangle must add to 90, so 46+44 = 90.
The 44 degree angle is adjacent to angle ADC, and it adds to angle ADC to form 180 degrees.
If x is the measure of angle ADC, then
44+(angleADC) = 180
44+x = 180
x = 180-44
x = 136
angle ADC = 136 degrees
For any parallelogram, the opposite angles are always congruent. Therefore, angle ABC is equal to angle ADC = 136, making ABC = 136 as well.
