Answer:
31.25 seconds
Step-by-step explanation:
Examine division
11.6 + 24.4 = 36 m < 50m
and 36 + 37.2 - 73.2m > 50m
50 - 36 = 14m
14 * 23.25/37.2 = 8.75 seconds
7.25 + 15.25 + 8.75 = 31.25 seconds
so it would take him 31.25 seconds to swim 50 meters.
I believe that Q is fourths? And Y is Yard.
Answer:
The answer is A 15,840, because 5,280 x 3 is equivalent to A

We will use trigonometric identities to solve this. I will use θ (theta) for the angle.
First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.
We can replace cotθ in the expression with 1/tanθ.

Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1
So now, we have:

Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.
We can replace secθ with 1/cosθ in our expression.

Simplify:

Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.
We can replace sinθ/cosθ with tanθ.
Now we have as our final answer:

Hope this helps!
