Answer:
c. Measuring the differences in blood pressure before, during, and after a procedure.
Step-by-step explanation:
Quantitative research use instruments to measure the variables we are studying. You could measure the variable by using any instrument, in this case the blood preasure during a procedure could be measured with an instrument called sphygmomanometer. Other options couldn't be measured with any instrument.
Answer:
Given
This is our initial premise.
2) Linear pairs of angles are supplementary
This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.

The definition of supplementary angles is that two angles are supplementary if their measures sum to

4) Substitution of 1. into 3.
As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.

Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
Parallel lines have the same slope. Therefore if given line is
then the slope of our line is 
.
We have the equation:
The line passes through (-1, -7). Put the coordinsted pf the point to the equation:
<em>add 2 to both sides</em>
Finally:
Answer:
<h2><u><em>
x = 69°</em></u></h2><h2><u><em>
V = 103°</em></u></h2>
Step-by-step explanation:
the sum of the interior angles in a triangles is 180°, take away from 180 the know angles (34° and 77°) and you will have your answer
180 - 34 - 77 = 69°
Now we find angle V
The angle V and the angle of 77 ° are on a straight line, so the sum is 180°, from 180° you subtract 77 ° and you have the value of V
180 - 77 = 103 °
