Answer: E
Step-by-step explanation:
In the picture attached, the Truth Table for the operator “OR” is shown. With it we can compute the next table:
p q ∧ r p ∨ (q ∧ r)
T T T
T F T
F T T
F F F
We want that p would be false and p ∨ (q ∧ r) would be true, which corresponds to the third row of the previous table.
The only row from the table of the question that satisfies this criterion is row E.
Answer:
18/12 or 1 6/12
or 3/2 or 1 1/12 or 1.5
a) x = 52°
b) x = 40°
a)
x = 26 + 26 = 52°
(Exterior angle = sum of interior angles)
b)
Angle CAD = Angle CDA = 180 - 110 = 70
x = 180 - 2(70)
x = 40°
The circle should be open and the arrow should go the other way.
