Answer:
Given that an image attached with this prove.
1. AD = AB, CD=CB 1. Given
2. OD = OB 2. By definition, the diagonal connecting vertec angles bisects the other diagonal
3. OA = OA 3. By reflexive property
4. triangle AOB = triangle AOD 4. By SSS congruence
5. angle AOB = angle AOD 5. By CPCTC
6. angle AOB = angle AOD = 90 6. both angles addup to 180
7. AC ⊥ DB 7. definition of right angles

Answer:
xy = 42.6282051282...
Step-by-step explanation:
0.78x/7 = 19/4y
0.78x * 4y = 3.12xy
19 * 7 = 133
3.12xy = 133
3.12xy/3.12 = 133/3.12
xy = 42.6282051282...
