Answer:
27 =x
Step-by-step explanation:
We can use the triangle angle bisector theorem
x+8 2x-5
-------- = ----------
10 14
Using cross products
14 (x+8) = 10 (2x-5)
Distribute
14x+112 = 20x -50
Subtract 14x from each side
14x-14x+112 = 20x-14x -50
112 = 6x - 50
Add 50 to each side
112+50 = 6x+50
162 = 6x
Divide by 6
162/6 = 6x/6
27 =x
Answer:
Median = 6.5 or 6 1/2
HOPE THIS HELPED! HAVE A GREAT DAY! :)
Answer:
AND
Step-by-step explanation:
I think the plus sign is supposed to be a x. The attached image contains the work.
Find the lengths AB, BC and AC.
length AB= √(4²+(-4)²) = √32
length BC = √(4²+7²) = √65
length AC = √(8²+3²) = √73
From the lengths of this triangle it can be seen that no side is equal to the other and also it is not a right triangle.
So, triangle ABC is a scalene.
