We have that
<span> points (−20, 21) and (0, 0)
Let 
A----> </span>(−20, 21)
B-----> (0, 0)

using a graph tool
see the attached figure

step 1

find the distance AB

<span>applying the Pythagorean theorem
</span>
AB²=20²+21²--------> 841---------> AB=√841-------> 29
AB=29 units

cos <span>Θ=20/29-------> 0.6897
</span>
the angle <span>Θ belong to the second quadrant
therefore
the cos</span><span>Θ is negative

the answer is
the cos </span>Θ is -0.6897

Step-by-step explanation:

A={6,9,11},B=ϕ

Here, B is empty set.

Therefore,

A∪B

=A∪ϕ

={6,9,11}

A intersection ϕ is ϕ I guess

A surveyor standing 67 meters from the base of the building measures the angle to the top of the building and finds it to be 36
ryzh [129]
Angle to the top of the building or base of the tower = 36 degrees
Angle to the top of the radio tower on the building = 46 degrees
Distance from the base at which the surveyor is standing = 67 meters
Let us assume the distance of the base of the tower from the surveyor = x1
Let us assume the distance of the top of the tower from the surveyor = x2
Then
tan(36) = x1/67
x1 = 67 tan(36)
and 
tan(46) - x2/67
x2 = 67 tan(46)
Now
x2 - x1 = 67 tan(46) - 67 tan(36)
            = 20.702
            = 20.7 m
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "b".
