Given:
In trapezoid  is the mid-segment of
 is the mid-segment of  .
.
To find:
The length of  .
.
Solution:
We know that the length of the mid-segment of a trapezoids is half of the sum of lengths of two parallel sides of the trapezoid.
In trapezoid  ,
,




Isolate variable terms.


Now,




Therefore, the length of  is 230.
 is 230.

Answer:
y=x
Step-by-step explanation:
y=mx+b
m is the slope
b is the y-intercept
Since the y-intercept is at the 0 axis, the y-intercept will be zero
So now the equation is looks like this:
y=mx (Since y=mx+0 doesn't make a difference)
Now find the slope
Which is 1
Thus y=x
