Answer:
Part A:

Part B:

Step-by-step explanation:
Part A:
The number of rivets=22 rivets
Probability that no rivet is defective= (1-p)^22
The probability that at least one rivet is defective=1-(1-p)^22
For 19% of all seams need reworking, probability that a rivet is defective is given by:

![(1-p)^{22}=0.81\\p=1-\sqrt[22]{0.81} \\p=0.0095](https://tex.z-dn.net/?f=%281-p%29%5E%7B22%7D%3D0.81%5C%5Cp%3D1-%5Csqrt%5B22%5D%7B0.81%7D%20%5C%5Cp%3D0.0095)
Part B:
For 9% of all seams need reworking, probability of a defective rivet is:
![1-(1-p)^{22}=0.09\\p=1-\sqrt[22]{0.91} \\p=0.0043](https://tex.z-dn.net/?f=1-%281-p%29%5E%7B22%7D%3D0.09%5C%5Cp%3D1-%5Csqrt%5B22%5D%7B0.91%7D%20%5C%5Cp%3D0.0043)
Answer:
60
Step-by-step explanation:
Since the sides are equal, the angles have to be equal
The angles of a triangle add to 180
180/3 = 60
Angle A = 60
