Answer:
31
Step-by-step explanation:
Sum of interior angles of a triangle is 180,
x + 5 + x - 5 + 108 = 180
x + x + 5 - 5 + 108 = 180
2x + 0 = 180 - 108
2x = 72
x = 72 / 2
x = 36
B = x - 5
= 36 - 5
B = 31
The correct answer is B. -6

Answer:
(6, 4)
Step-by-step explanation:
The midpoint is found as the average of the coordinates of the end points.
M = (A +B)/2
M = ((9, 1) +(3, 7))/2 = (9+3, 1+7)/2 = (12, 8)/2
M = (6, 4)
The midpoint of segment AB is (x, y) = (6, 4).
The equation of the line that is perpendicular to 4x - 3y = 10 through the point (-2,4) is
<u>Solution:</u>
Given, line equation is 4x – 3y = 10
We have to find a line that is perpendicular to 4x – 3y = 10 and passing through (-2, 4)
Now, let us find the slope of the given line,
We know that, slope of a line slope of perpendicular line = -1
Now, slope of our required line = and it passes through (-2, 4)
<em><u>The point slope form is given as:</u></em>
Hence the equation of line is found out
