A biologist wants to know the width w of a river in order to properly set instruments for studying the pollutants in the water.

belka [17]

Answer: The river is 148.3 feet wide.

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The triangle formed is a right triangle.

Using SOH CAH TOA

$tan 56 = \frac{x}{100}$

Multiplying 100 in both sides

$x = 100 \times tan56$

$x = 100 \times 1.4826$

$x = 148.26$

Rounding to the one decimal place

$x = 148.3$

Hence river is 148.3 feet wide. .............. Answer

Hope it will help :)

Help me find the answer to this area of a kite problem

julia-pushkina [17]

Answer:

Below in bold.

Step-by-step explanation:

Area of a kite = 1/2 * D1 * D2 were D1 and D2 are the 2 diagonals

D1 = 5 + 2.5 = 7.5 and D2 = 2*44444.5 = 9

So area = 1/2 * 7.5 * 9

= 33.75.
