-it is given that angle A and angle C are equal, both 90
-angle ABD and angle CDB are equal because they are alternate interior angles
- side DB and side DB are the same length
- two triangles are equal because of AAS

24 = -v/3 (first you multiply 3 to each side)
<u>×3 ×3</u>
<u />72 = -v (then you divide -1 from each side)
-72 = v<u><u /></u><u />
