Answer:
Option C 3 + 4 = 9 or 5 · 2 = 11 is correct answer
Step-by-step explanation:
Disjunction states that if we have p or q then the disjunction is true if either p is true or q is true or p and q are true.
The disjunction is false when both p and q both are false.
1. 2 · 3 = 6 or 4 + 5 = 10
Disjunction is true because 2.3 =6 is true while 4+5=10 is false
2. 5 - 3 = 2 or 3 · 4 = 12
Disjunction is true because 5-3 =2 is true and 3.4=12 is also true.
3. 3 + 4 = 9 or 5 · 2 = 11
Disjunction is false because 3+4 =7 and not 9 and 5.2 =10 and not 11. Since both are false so, this disjunction is false.
4. 6 · 2 = 11 or 3 + 5 = 8
Disjunction is true because 6.2=12 and not 11 is false but 3+5 = 8 is true.
So, Option C 3 + 4 = 9 or 5 · 2 = 11 is correct answer.
Answer:
Perpendicular Line Theorems
Step-by-step explanation:
If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. If two sides of two adjacent angles are perpendicular, then the angles are complementary. If two lines are perpendicular, then they intersect to form four right angles.
