Answer:
15.24 millimeters
Step-by-step explanation:
6 * 2.54 = 15.24 mm.
To find the inverse, interchange the variables and solve for y.
f^-1 (x) = 4 + x/2
Answer:
A
Step-by-step explanation:
20 x 2 = 40
30 x 2 = 60
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°
