Answer:
They are a system of equations?
Step-by-step explanation:
Not sure if this is what you are asking
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.
Basically add up the given side lengths and subtract that from 180 for the triangles
