Answer:  a.  (2.5, 300°)  and  (-2.5, 120°)

               b.  (4, 270°)    and   (-4, 90°)

<u>Step-by-step explanation:</u>

Polar coordinates are written as (r, θ)    where

  • r is the radius
  • θ is the angle

In the first graph, the radius is 2.5 and the angle is 300° --> (2.5, 300°)

You can also list the radius as -2.5 at angle 120° --> (-2.5, 120°)

                                                                           ↓

                                                                    (300 - 180)

In the second graph, the radius is 4 and the angle is 270° --> (4, 270°)

You can also list the radius as -4 at angle 90° --> (-4, 90°)

                                                                      ↓

                                                                (270 - 180)

HELP ASAP!!! A man is 6 feet 2 inches tall. To find the height of a tree, the shadow of the man and the shadow of the tree were
Whitepunk [10]

1 ft = 12 inches

6 ft = 72 inches (multiply both sides by 6)

6 ft + 2 inches = 72+2 = 74 inches

6 ft, 2 inches = 74 inches

--------------------

1 ft = 12 inches

2 ft = 24 inches

2 ft + 1 in = 24+1 = 25 inches

2 ft, 1 in = 25 inches

--------------------

1 ft = 12 inches

3 ft = 36 inches

3 ft + 7 in = 36+7 = 43 inches

3 ft, 7 in = 43 inches

--------------------

To rewrite the problem a bit in equivalent form, we have a man who is 74 inches cast a shadow that is 25 inches long. The tree has a shadow of 43 inches. We want to find the height of the tree, which for now we'll call x

(tree height)/(tree shadow) = (person height)/(person shadow)

x/43 = 74/25

25x = 43*74

25x = 3182

x = 3182/25

x = 127.28 inches

The tree is 127.28 inches tall which is the same as 10 ft, 7.28 inches

because 127/12 = 10 remainder 7, then we add on the 0.28 portion

Express sin A, cos A, and tan A as ratios ​
vlabodo [156]
<h3>Answer: Choice B</h3><h3>sqrt(3)/2,    1/2,   sqrt(3)</h3>

================================================

Explanation:

Sine of an angle is the ratio of the opposite side over the hypotenuse. For reference angle A, the opposite side is BC = 6sqrt(3). The hypotenuse is the longest side AB = 12

Sin(angle) = opposite/hypotenuse

sin(A) = BC/AB

sin(A) = 6sqrt(3)/12

sin(A) = sqrt(3)/2

---------------

Cosine is the ratio of the adjacent and hypotenuse

cos(angle) = adjacent/hypotenuse

cos(A) = AC/AB

cos(A) = 6/12

cos(A) = 1/2

---------------

Tangent is the ratio of the opposite and adjacent

tan(angle) = opposite/adjacent

tan(A) = BC/AC

tan(A) = 6sqrt(3)/6

tan(A) = sqrt(3)
