<h3>Answer: 400 </h3>

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

Work Shown:

A = area of parallelogram

A = base*height

A = 20*16

A = 320

B = area of triangle at the very top

B = (1/2)*base*height

B = (1/2)*20*8 ... note: opposite sides of parallelogram are equal

B = 80

C = total area of entire figure

C = A+B

C = 320+80

C = 400

Find the cosine of R.

JulijaS [17]

Answer:

$cos(R) = \frac{\sqrt{15}}{5}$

Step-by-step explanation:

To find the cosine of <R, apply the following trigonometric ratio formula:

$cos(R) = \frac{adjacent}{hypotenuse}$

Adjacent = 3

Hypotenuse = √15

Plug in the values into the formula

$cos(R) = \frac{3}{\sqrt{15}}$

Multiply the numerator and denominator by √15 to rationalize.

$cos(R) = \frac{3 \times \sqrt{15}}{\sqrt{15} \times \sqrt{15}}$

$cos(R) = \frac{3\sqrt{15}}{(\sqrt{15})^2}$

$cos(R) = \frac{3\sqrt{15}}{15}$

$cos(R) = \frac{\sqrt{15}}{5}$

Air is a mixture of many gases. For example, 0.78 of air is nitrogen, and 0.93% is argon. Is there more nitrogen or argon in air

Tems11 [23]

Argon because when you compare the place values, 0.78 which is the amount of nitrogen and 0.93, the amount of argon in air. 0. Is the same so move to the next number, 0.7 and 0.9. 9 is the largest number so 0.93, ( Argon) is more
