Given the Trapezoid ABCD<br><br> Find the length of AD <br><br> Pls hellpppp
matrenka [14]

Given:

In trapezoid ABCD, AD\parallel BC, MN is the mid-segment of ABCD, AD=30x-10,MN=31x+1,BC=30x+28.

To find:

The length of AD.

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 ABCD,

MN=\dfrac{AD+BC}{2}

31x+1=\dfrac{30x-10+30x+28}{2}

31x+1=\dfrac{60x+18}{2}

31x+1=30x+9

Isolate variable terms.

31x-30x=9-1

x=8

Now,

AD=30x-10

AD=30(8)-10

AD=240-10

AD=230

Therefore, the length of AD is 230.
