1, 3, and 5 would be my best guesses but I’m not 100 percent sure
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°
Answer:256
Step-by-step explanation:To divide power of the same base,subtract the denominator's exponent.Subtract 4 from 7 to get 4.Then calculate 4 to the power of 4 and get 256
The answer is E hope this helps
