Which pair of angles must be supplementary
2 answers:
Answer:
B.
Step-by-step explanation:
We have been given an image of intersecting lines. We are asked to find the pair of angles that must be supplementary.
We know that two angles are supplementary when they add up-to 180 degrees.
Upon looking at our given image, we can see that the measure of angle 2 and measure of angle 5 is 90 degrees. So these angles will add up-to 180 degrees, therefore, option B is the correct choice.

Answer:
<h2>b = -9</h2>Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The formula of a slope:
We have the points M(4, 3) and N(7, 12). Substitute:
Therefore we have the equation:
Put the coordinates of the point M to the equation:
<em>subtract 12 from both sides</em>
