Kayson is looking at two buildings, building A and building B, at an angle of elevation of 73' Building A is 30 feet away, and b
wlad13 [49]

Answer:

Building B, it is around 16 35 feet taller than building A ( C )

Step-by-step explanation:

<u>Calculating  the height of Building A </u>

Height = opposite ( ? )

∅ = 73°

base/adjacent  = 30 ft

∴ Height = Tan 73° * base

               = 3.2709 * 30 =  98.127 ft

<u>Calculating the height of building B </u>

∅ = 73°

base/adjacent  = 35 ft

∴ height = Tan 73° * base

              = 3.2709 * 35 = 114.4815

Therefore we can say Building B is Taller by approximately 16.35 feet

The speed of the current in a creek is 2mph. A person can kayak 10 mi upstream in the same time that it takes him to kayak 14 mi
ad-work [718]

Answer:

  2 hours

Step-by-step explanation:

The relation between time, speed, and distance is ...

  time = distance/speed

For a kayak speed of k miles per hour in still water, the speed upstream is (k-2) and the speed downstream is (k+2). Over the distances given, the times are the same, so we can write ...

  10/(k-2) = 14/(k+2)

Multiplying by (k+2)(k-2) gives ...

  10(k+2) = 14(k -2)

  10k +20 = 14k -28 . . . . . eliminate parentheses

  48 = 4k . . . . . . . . . . . . . . add 28-10k

  12 = k

Then the time for 28 miles downstream is ...

  time = 28 / (12 +2) = 2 . . . . hours

It will take the person 2 hours to kayak 28 miles downstream.
