Step-by-step explanation:
16. C, <AOB = 20
The total angle (<AOC) is equal to the sum of the angles inside of it (<AOB and < BOC).
<AOC= <AOB + <BOC
47=<AOB+27
<AOB=20
17. 24
Area of a square = 
36= 
s= 6
One side is 6
The perimeter of a square is 4(s)
4(6) = 24
Word of encouragement:
Good luck!
The slope formula:

m - a slopeb - y-intercept
We have:

and point

Substitute:
Answer: A.
(-X-13)+(X+13)+(X-13)
The positive x and negative x cancel out and equal zero. The positive 13 and negative 13 cancel and equal zero also. Then you are left with (x-13)
Total area
= 2(5 × 15) + (12 - 5 - 5)(15 - 8)
= 150 + 14
= 164 m²
