150 because if you take 180 and subtract 30 u get 150
The angle subtended by two chords is half the enclosed arc measure. If we imagine one of the chords getting shorter and shorter this remains true. In the limit the shrinking chord becomes a tangent, and the angle is still half the arc measure.
Answer: 70 degrees
The answer is 0.2450
To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the probabilities of each event are multiplied.
In this situation, we have two events occurring simultaneously:
1. Nathan is not allergic to penicillin. The probability that Nathan is not allergic to penicillin is:
1 - the probability of having the allergy.
If the probability of having the allergy is 75% = 0.75, then the probability that Nathan is not allergic to penicillin is:
1 - 0.75 = 0.25
2. The probability that the test is accurate: 98% = 0.98
By using the multiplication rule:
0.25 × 0.98 = 0.245
Therefore, the probability after the test that Nathan is not allergic to the drug is 0.245 = 24.5%.

Answer:
Option C: x = 6
Step-by-step explanation:
Hi There!
7 + 5 (x - 3) = 22
=> 7 + 5x - 15 = 22
=> 5x = 22 - 7 + 15
=> 5x = 30
=> x = 30/5
=> x = 6
x = 6 makes the statement true.
Thank you,
Eddie
