hope this helped is not sorry
Answer:
a = 33 degrees, b = 147 degrees
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees, and to solve for the angle on the other side of 109 degrees is 71 degrees, so to solve for a, have 180 minus 71 and 76. Then the sum of 71 and 76 is angle b since its the result of a subtracting from 180.

hope this helps!!!!!
Measure the sides. And when you get all of the sides add them I'll and get the perimeter I think.
Answer:
Events E and F are independent.
Step-by-step explanation:
E = {multiple of 3} = {3, 6, 9, 12}
P(E) = 4/12
F = {even number} = {2, 4, 6, 8. 10, 12}
P(F) = 6/12
E and F = {even and multiple of 3} = {6, 12}
P(E∩F) = 2/12
In order for two events to be independent the following relationship must be true:
![P(E)*P(F) = P(E\cap F)](https://tex.z-dn.net/?f=P%28E%29%2AP%28F%29%20%3D%20P%28E%5Ccap%20F%29)
Testing this property:
![P(E)*P(F) = \frac{4}{12}*\frac{6}{12}=\frac{24}{144}=\frac{1}{6} \\P(E\cap F) = \frac{2}{12}=\frac{1}{6} \\P(E)*P(F) = P(E\cap F)](https://tex.z-dn.net/?f=P%28E%29%2AP%28F%29%20%3D%20%5Cfrac%7B4%7D%7B12%7D%2A%5Cfrac%7B6%7D%7B12%7D%3D%5Cfrac%7B24%7D%7B144%7D%3D%5Cfrac%7B1%7D%7B6%7D%20%20%20%20%5C%5CP%28E%5Ccap%20F%29%20%3D%20%5Cfrac%7B2%7D%7B12%7D%3D%5Cfrac%7B1%7D%7B6%7D%20%5C%5CP%28E%29%2AP%28F%29%20%3D%20P%28E%5Ccap%20F%29)
The relationship holds true, thus events E and F are independent.
