Answer:
Only 1 plane containing line L can be drawn parallel to plane P.
Step-by-step explanation:
Line L is an axis of an infinite number of planes that can contain it. Line L is a straight line suspended over or below plane P.
All the planes that can contain line L would be almost infinte. Spinning around this axis of line L, the planes that can contain line L will be always be at an angle to plane P except for one position. In this position the plane containing Line L would face straight up to the plane P, hence, this is the only parallel case.
Hope this Helps!!!
Answer:

Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = 
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = 
90* = 10
Answer:
3(10 + 4) = 34 + 6 = 40
Step-by-step explanation:
Barbara has 30 school supplies plus an extra 4. Lisa on the other hand has 6. In total they have 40.
