Answer:
∠ BAC = 80°
Step-by-step explanation:
The sum of the interior angles of quadrilateral ACDB = 360°
DB and DC are tangents to the circle, thus
∠ DBA = ∠ ACD = 90° ( angle between tangent/ circle at point of contact )
Thus
∠ BAC + 90° + 90° + 100° = 360°
∠ BAC + 280° = 360° ( subtract 280° from both sides )
∠ BAC = 80°

And area of a square it = length ²
The result will give s a perfect square for an integer number.
A. 9 square ft = perfect square
B. 12 square ft = not perfect square
C. 63 square ft =not perfect square
D. 81 square ft= perfect square
So the ones that are not perfect squares Is the answer to the question
