explanation: (5-0)/(7-0) = 5/7
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°
y = 3x - 4 answer x = 11/3
4x + 3y = 1 answer -3/4y + 1/4
2-3x = y answer -1/3y + 2/3
Let me know if you have questions
The answer would be 10,856 because there are 10,800 seconds in three hours so you divide 12,800 by 10,846 and it will give you the cost of how much it was spent.
