Answer:
Complementary, 65
106+x=180
Step-by-step explanation:
Complementary angles add to 90, Supplementary angles add to 180
These are complementary angles
x+25 = 90
Subtract 25 from each side
x+25-25 =90-25
x = 65
The next questions they are supplementary angles because they add to 180
Subtract 106 from each side
106-106+x=180-106
x=74

Answer: 0.82
The probability of the computer not containing neither a virus nor a worm is expressed as P(∩) , where P() is the probability that the event V doesn't happen and P() is the probability that the event W doesn't happen.
P()= 1-P(V) = 1-0.17 = 0.83
P()=1-P(W) = 1-0.05 = 0.95
Since and aren't mutually exclusive events, then:
P(∪) = P() + P() - P(∩)
Isolating the probability that interests us:
P(∩)= P() + P() - P(∪)
Where P(∪) = 1 - 0.04 = 0.96
Finally:
P(∩) = 0.83 + 0.95 - 0.96 = 0.82
