Answer:

x = -2

Step-by-step explanation:

Picture attached, shows a weighing scale in the balanced form,

So weight of elements on the left = Weight of the elements on the right

Left side of the scale = weight of x + weight of 1

                                   = x(2) + 1(6)

                                   = 2x + 6

On the right side of the scale = Weight of (-x) + weight of (-1)

                                                 = (-x)(2) + (-1)(2)

                                                 = -2x - 2

Since, both the sides are balanced,

Therefore, equation which models the situation is,

(2x + 6) = -(2x + 2)

(2x + 6) + (2x + 2) = 0

4x + 8 = 0

4x = -8

x = -2

Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. To the nearest foot,
Firlakuza [10]
The problem says that <span>Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:
</span>
 Tan(α)=Opposite leg/Adjacent leg

 α=30°
 Opposite leg=x
 Adjacent leg=200 feet

 When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:

 Tan(α)=Opposite leg/Adjacent leg
 Tan(30°)=x/200
 
 You must clear "x":

 x=200xTan(30°)

 Therefore, the value of "x" is:

 x=115 feet
<span>
 How high above the ground the is the helicopter?

 The answer is: 115 feet</span>

The axis of the sphere below is 16 units in length. What is the surface area of the sphere?.
Nataly_w [17]
There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
                                            = 4 * pi * (8)^2
                                            = 4 * pi * 64
                                            = 256pi
I hope that this answer has come to your help.

Please help! you have to find the surface area of the inage below!
viva [34]
Your answer would be 64 in².

To find the surface area, you just need to find the area of each of the shapes shown and add them together.
We can find the area of one of the triangles by doing:
(base × height)/2
(6 × 4)/2 = 24/2 = 12

As there are 4 identical triangles, the area of all of them would be 12 × 4 = 48 in².

Now we need to find the area of the square in the middle, which would be 4 × 4 = 16 in².

Adding these together gives us 16 + 48 = 64 in²

I hope this helps!

Please help ASAP! 40 PTS
tester [92]

Answer:

see below

Step-by-step explanation:

1.  < 4 is the exterior angle of a triangle   given

2.  <1 + <2 + <3 =180   basic property of triangles

3.  <3 + <4 are a linear pair    <3 and <4 are adjacent and form a straight line

4. <3 and <4 are supplementary angles  supplementary angles are linear pairs

5.  <3 + <4 = 180   The definition of supplementary angles are that they add to 180 degrees

6.  <1 + <2 + <3 = <3+ <4  Substitute <3 + <4  for 180 in equation from step 2

7 <1 + <2 = <4   Subtract <3 from each side using the subtraction property of equality
