The diagram below shows a student using a clinometer to measure the height of a flagpole. When the student stands 40 feet away f
AVprozaik [17]
The correct answer is the flagpole is <span>33 feet high</span>.

Explanation:
Please refer to the attached picture.

We know:
CD = 40 feet
AC = 5 feet
∠BDC = α = 35°

Using trigonometry, we know that the definition of the tangent of an angle is the ratio between the opposite side and the adjacent side, therefore:
tan α = BC / CD

Solving for BC:
BC = CD · <span>tan α
      = 40 </span>· tan (35)
      = 28 feet

In order to find the height of the flagpole, we need to add the distance of the clinometer from the ground:
AB = BC + AC
      = 28 + 5
      = 33

Hence, the flagpole is 33 feet high.

A family plans a road trip from Fairbanks to Newbury. The distance between the two cities is 240 miles when traveling on the hig
alex41 [277]

Using proportions, it is found that the family will drive 482.8 km on the new route.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:

D = 1.25 x 240 = 300 miles.

Since there are are approximately <u>48.28 kilometers in 30 miles</u>, and 300/30 = 10, the distance in kilometers is given by:

D = 48.28 x 10 = 482.8 km.

Given the following: What is the value of x? What is the value of y? What is the m∠A? Show all work.
kondaur [170]

Answer:

angle A=angle C

angle B =angle D

to find x

x + 45 = 3x - 85 \\ x - 3x =  - 85 - 45 \\  - 2x =  - 130 \\ x = 75

to find y

x + 45 + 3x - 85 + y + y = 360 \\ 4x  + 40 + 2y = 360 \\ 4(75) + 2y = 360  - 40\\ 300 + 2y = 320 \\ 2y = 20 \\ y = 10
