Answer:
8/5
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (10- -6)/(5 - -5)
= (10+6)(5+5)
= 16/10
= 8/5
Answer:no
Step-by-step explanation:
Angles ECD and CEF add to 180
40+140 = 180
So that means we have EF parallel to CD (due to the same side interior angle theorem)
--------------
Angles BCE and ECD combine to 30+40 = 70, which is congruent to angle ABC = 70 as well.
In other words, this shows angle ABC = angle BCD. Both of these angles are alternate interior angles. Since they're congruent, they lead to AB being parallel to CD.
--------------
So far we have
AB || CD
CD || EF
Using the transitive property, we can then link the two statements to say AB || EF. Think of a chain where CD is the common link. We go from AB to CD, then from CD to EF. So we can just take a single path from AB to EF.
It's like saying "P --> Q and Q --> R, therefore P --> R"
where is the question?????????
Answer:
<h2>9</h2>
Step-by-step explanation:
If Point H is on line segment GI, then GH+HI = GI
Given the following parameters
GH = x + 6,
HI = x + 5, and
GI = 3x + 8
To determine the length of GH, we need to get the value of x first. To get x we will substitute the given parameters into the formula as shown;
x+6+(x+5) = 3x+8
2x+11 = 3x+8
collect like terms;
2x-3x = 8-11
-x = -3
divide both sides by -1;
-x/-1 = -3/-1
x = 3
Since GH = x+6
GH = 3+6
GH = 9
<em>Hence the numerical length of GH is 9</em>
