Answer:
43.5 unit^2.
Step-by-step explanation:
Area of the triangle
= 1/2 * base * height
= 1/2 * AB * AC.
AB = √ [(6-1)^2 + (6-8)^2] = √29
AC = √ [(8 - (-7))^2 + (1 - (-5)^2] = √261
So the area = 1/2 * √29 * √261
= 43.5
Answer:
8.66
Step-by-step explanation:
root 75 is also 5 root 3 (after simplifying)
when that is converted into a decimal we get
8.660254038...
Rounding to the nearest hundred of that number we focus on these two numbers
8.6<u><em>60</em></u>254038...
As a result to the nearest hundreth is 8.66
Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point 
value of first point) divided by (x value of second point 
value of first point):

The slope for a perpendicular line is 2.
Answer:
If a line is parallel to another line, the slopes of both lines are the same. So far the equation would be, y=7/6x+b. To find the value of b, you substitute the given point into the equation. -2=7/6(-1)+b, -2=-7/6+b, b=-5/6. So the equation of the line is y=7/6x-5/6.

Answer:
Angle 1: 168
Angle 2: 12
Explanation:
I did the math! basically, i did 168-156, and got 12. Then i added, 168+12, and got 180. So i know that both angles together make 180 degrees, which is the definition of supplementary angles.
