Answer:
180
Step-by-step explanation:
I need to draw a picture to explain.
There's an identity
sec^2 x = 1 + tan^2 x
so here we have
sec^2 theta = 1 + (3/8)^2 = 73/64
sec theta = sqrt 73 / 8 or 1.068 to nearest thousandth
Solution :
We have to prove that
(De-Morgan's law)
Let
then
and 
and so
and
.
Thus,
and so 
Hence,
.........(1)
Now we will show that 
Let
⇒
Thus x is present neither in the set A nor in the set B, so by definition of the union of the sets, by definition of the complement.
and 
Therefore,
and we have
.............(2)
From (1) and (2),
Hence proved.
Answer:
200 feet
Step-by-step explanation:
Area of the warehouse 
Let the length of the warehouse=l
The warehouse's width is exactly
of its length
Therefore: Width of the warehouse
Area =Length X Width
Therefore:

1) Answer: A
because trangles RST is similar to VUT as:
<RST=<VUT=55 (Angle)
<RTS=<VTU=90 (it seems right angled) Angle
So by AA similarity...(two angles similarity is enough)
2) Answer:B
y+z=x because exterior angle of a triangle (which is x) must be equal to sum of non-adjacent (y and z) interior angles.
3) Answer: A should be right choice. Step 1 is wrong here which is,
m<m + m<n + m<p=180 (wrong)
It should be:
m<m + m<n + m<0=180 (right)
