Answer:

Step-by-step explanation:
We have been provided a graph of a triangle and we are asked to find the length of segment DE.
Angle bisector theorem states that if a ray bisects an angle of a triangle, then it bisects the opposite side of triangle into segments that are proportional to other two sides.
By angle bisector theorem we can set proportions of the given sides as:

Upon substituting our given values in above proportion we will get,

Upon multiplying both sides of our equation by 2 we will get,



Therefore, the length of segment DE is 4 units.
Answer:
x=2 and y= -1
Step-by-step explanation:
substitute x value in equation 2
2(5y+7)+4y=0
10y+14+4y=0
14y = -14
y= -1
here,
x= 5(-1)+7
x= -5+7
x=2
