(4^2+8^2)^.5 = 8.944
It's not 12.
So 4,8,12 can't be the side lengths of a right triangle.

If 0° ≤ θ ≤ 90° and cosθ = 11/15 , what is the value of sin (90° - θ)?
igor_vitrenko [27]
11/15=0.7333
cos^{-1}(0.7333) =42.83342
sin(90-47.166572) = 0.7333

first, find the numeric value for 11/15
second to find theta, simply do the <em>inverse</em> cos (which is cos^-1) of the first answer.
now you know theta, just do the sin of 90 - theta and that's it!

since you know whatr cos(theta) is, you just take the inverse cos of that number to get theta and 'reverse' cos, essentially. you are just solving for theta, by reversing the cos function with cos^-1

If it requires 6 pounds of wild caught animals to create 1 pound of salmon, what percent of the wild caught animals are wasted?
Oduvanchick [21]

The percentage of animal wasted is the number of animal wasted over 100

85.7%  of the wild caught animals are wasted

<h3>How to calculate the animal wasted</h3>

From the question, we have:

Animals caught = 6 pounds

Salmon = 1 pound

The total weight in the system is:

Total = 6 pounds + 1 pound

So, we have:

Total = 7 pounds

The percent of wild caught animals wasted is then calculated as:

\%Wasted = \frac{6}{7} * 100\%

Simplify

\%Wasted = 85.7\%

Hence, 85.7%  of the wild caught animals are wasted

What is the length of line segment s a? 1.89 ft 2.43 ft 3 ft 7 ft
Slav-nsk [51]

The ratio of the sides will be constant. Then the value of the length of line segment SA will be 3 ft.

The missing diagram is given below.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The triangles ΔABC and ΔSBT are the similar triangles.

Then the ratio of the sides will be constant.

BS / SA = BT / TC

10 / SA = 9 / 2.7

      SA = 3

Then the value of the length of line segment SA will be 3 ft.

More about the triangle link is given below.
