Answer:

13. Sin<A = 77.3°

14. Tan<A = 77.3°

15. Cos<A = 77.3°

Step-by-step explanation:

<em>From</em><em> </em><em>Trigonometry</em><em>.</em>

13.

\sin(a)  =  \frac{opposite}{hypotenuse}

Sin<A =

40÷41

<A = sin-1 (40÷41)

<u><A = 77.3°</u>

14.

\tan(a)  =  \frac{opposite}{adjacent}

Tan<A= (40÷9)

<A = tan-1 (40÷9)

<u><A = 77.3°</u>

15.

\cos(a)  =  \frac{adjacent}{hypotenuse}

Cos<A = (9÷41)

<A = cos-1 (9÷41)

<u><A = 77.3°</u>

What is the length and width of a 864 square feet
spayn [35]
The area doesn't tell you the dimensions. There are an infinite number of different answers, all with the same area but different dimensions.
Here are a few:
1 ft by 864 ft
2 ft by 432 ft
3 ft by 288 ft
4 ft by 216 ft
8 ft by 108 ft
16 ft by 54 ft
24 ft by 36 ft
27 ft by 32 ft.

The area of each of these is 864 square feet.

I need help please.

Answer is C).

One way to find the answer is to multiply the $54 by .30 (which is 30%converted to a decimal). Doing this will give you what 30% of $54 is.
This gives you 16.2
Since the question is asking what 30% off the price is, subtract the 16.2 from the $54.
