Answer:

C

Step-by-step explanation:

Let us first write an equation. Using the SOHCAHTOA rule, we should know that the tangent of an angle equals it's \frac{opposite}{adjacent}. The opposite of our given 20° angle is 9, and the adjacent side is <em>x</em>.

tan(20°)=\frac{9}{x}

0.364=\frac{9}{x} \\x=\frac{9}{0.364}\\x=24.7

<u>C</u>

The owner of the Rancho Bar X wishes to use 2400 yards of fencing to enclose a rectangular piece of grazing land along the strai
aleksandrvk [35]

Answer:

Step-by-step explanation:

Let length be x and breadth be y .

Along the river no fencing is required so total boundary line of the rectangular land = x + y + y = x + 2y

add divider to it so total length

= x + 2y + y = x + 3y

x + 3y = 2400

area A = xy

y ( 2400 - 3y ) = A

2400y - 3y² = A

For maximum area dA / dy = 0

2400 - 6y = 0

y = 400 yards.

x = 1200 yards

largest area = xy

= 48000 sq yards.

Find w.<br><br> A. 8.9<br><br> B. 0.05<br><br> C. 0.08<br><br> D. 5.2
enyata [817]

Answer:

Step-by-step explanation:

Measure of angle V = 180 - 62 - 36 = 82 degrees

So by the law of sines, 10/sin(82 deg) = w/sin(62 deg)

w = [10sin(62)]/sin(82)

from here just plug this into a calculator
