Answer:
irrational this is because when you divide - 9 / 4 gives you an irrational answer
Answer:
30
Step-by-step explanation:
The line is divided up into 3 parts, a part of 3, a part of 4, and a part of 1. If we had those parts together we get 8 meaning if we divided the line into equal parts that also fit into a, b, and c there would be 8. We can than divide the line into 8 parts which would be 10 each since a line is 180 degrees. Since a is 3 than a gets 3 of those parts meaning a would be 30

Answer:
E
Step-by-step explanation:
The problem says that triangle BDC lies in the plane k, which means that whatever angle is formed by another point beyond this plane with any of the three segments that form BDC (BD, DC, and BC) is the same as the angle formed by the line connecting the point and the plane.
Here, we're given that AD⊥DC, which means AD forms a 90° angle with DC. Then, since DC is already on the plane, we already know for sure that AD is definitely perpendicular to plane k.
Thus, the answer is E (none of these).
