Artyom0805 [142]

Answer:

306.8 feet

Step-by-step explanation:

Refer the attached figure .

A surveyor moves 160 feet away from the base of the pole i.e. ED = 160 m

Referring the image .

AC=ED=160 m

A transit i.e. AE is 6 feet tall.

AE = CD=6 feet

With a transmit the angle of elevation to the top of the pole to be 62° i.e. ∠BAC = 62°

To Find BC , use tigonometric ratio.

Tan\theta = \frac{Perpendicular}{Base}

Tan 62^{\circ}=\frac{BC}{AC}

Tan 62^{\circ}=\frac{BC}{160}

1.88*160=BC

300.8=BC

Now, the height of the pole = BC+CD =300.8+6=306.8 feet

Hence the height of the pole is 306.8 feet

anygoal [31]

Answer:

1.  (x+8)(x-4)

2.  3x-20

Step-by-step explanation:

1.  x² + 4x – 32

x² + 8x - 4x - 32

x (x+8) - 4 (x+8)

one of the x+8's is cancelled out then you have (x+8)(x-4)

The temperature dropped 5 degrees every hour during 8 hours. How much the temperature drop in all?
Murrr4er [49]

Answer:

<h3>40 degrees</h3>

Step-by-step explanation:

If the temperature dropped 5 degrees every hour, this can be expressed as;

5 degree = 1 hour

To get the total number of degree dropped fro 8hours, we will say;

x degree = 8hours where x is the temperature drop in all

Solving both equality

5 degree = 1 hour

x degree = 8 hours

cross multiply

x * 1 = 5 * 8

x = 40 degrees

<em>Hence the total temperature drop in all is 40°</em>
