A person is standing 200ft from a tower. She can see the top of the tower at a 42 degree angle of elevation. Her eyes are 5ft ab

Oxana [17]

Answer:

C. 185 ft

Step-by-step explanation:

The work is in the attached picture file, if you need it. Basically the question sets up a right triangle, for which the base is 200 and the height is the goal that you are solving for. It is given that the angle between hypotenuse and base is 42 degrees. For this you use tangent to say that

tan(42) = h / 200

200 tan (42) = h

h = 180 feet.

But then you must remember that this triangle starts 5 feet off of the ground. So you add the 5 feet and get 185 feet as the height of the tower.

What is 100 minus 6x equals 160 - 10x answer

In-s [12.5K]

10 - 6x = 160 - 10x
+6x +6x

-10 + 6 = -4

10 = 160 - 4x
-160

10 - 160 = -150

-4x = -150

-4x/4 = -150/-4

x= 37.5

4n=1/2(2n-12) check the solution to the example problem by replacing n in the original equation with -2 and evaluating both side

worty [1.4K]

Answer:

The true statement is that the expression is satisfied for n = -2.

Step-by-step explanation:

Given:

$4n = \frac{1}{2}\times (2n-12)$

To check:

Left hand side = Right-hand side ( for n = -2)

Proof :

For n = -2

Consider Left hand side of the equation given above.

∴ Left hand side = 4n

= 4×(-2) ......................for n = -2

= -8

Consider Right-hand side of the equation given above

∴ Right-hand side = $\frac{1}{2}\times (2n-12)$

$=\frac{1}{2}\times (2\times(-2) - 12) \\= \frac{1}{2}\times (-4 - 12)\\ =\frac{1}{2}\times (-16)\\ =-8$

Now we get Left hand side equal to Right hand side

i.e. Left hand side = Right hand side

i.e. $4n = \frac{1}{2}\times (2n-12)$ is true for n = -2
