Answer:
<em>Proof in explanation</em>
Step-by-step explanation:
<u>Trigonometric Identities</u>
The basic trigonometric identity is:
We'll use it and some basic algebra to prove that, given:
And
Then
From the equation:
We have:
The equation
Can be rewritten as
Replacing [1]:
Taking the common factor:
The expression in parentheses is 1, thus:
Dividing by
Replacing in
We have
Dividing by
Now:
This expression is 1, thus it's proven:
I found the image that accompanied this problem.
We need to solve for the area of the sector.
A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347
Answer is C. 18.5 square meters.
