Answer:
26 should be the median
Step-by-step explanation:
is what I got
Given:
In triangle ABC, AE is the angle bisector.
To find:
The value of x.
Solution:
According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side of the triangle into two parts. These two parts are proportional to the other two sides of the triangle.
Using the angle bisector theorem, we get
On cross multiplication, we get
Divide both sides by 2.
Therefore, the value of x is 6.
Answer:
x = 9 is the x-intercept.
Step-by-step explanation:
We have given the coordinates (-6,10) and (12,-2).
We have to find the x-intercept of the line containing these points.
First we find the slope m by using these points.
We know that m = (y₂-y₁)/(x₂-x₁)
m = -2/3
The general form of the equation of line is :
y = mx + c
Where c is the y intercept.
Using the first coordinate to find c .
10 = (-2/3)(-6) +c
c = 6
So, the required equation is :
y = (-2/3)x+6
We have to find the x-intercept.
For this we put y=0
(-2/3)x+6 = 0
2/3 x = 6
x = 6(3/2)
x = 9 is the x-intercept.
-9h - 6 + 12h + 40 = 22
3h + 34 = 22
3h = -12
h = -12/3
h = -4
