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
Step-by-step explanation:
Answer:
|-4|+9
Step-by-step explanation:
|-4| is 4 and adding that to 9 equals 13
When it’s |-4+9|, it ends up being 5 because the absolute value of a positive number doesn’t change
