39.65 is the approximate value of arccos0.77
26.90 is the answer. hope this helps!
Answer:
350
Step-by-step explanation:
12% = 0.12
42 / 0.12 = 350
To determine the scale factor of the dilation, we determine the distances between the endpoints of the two lines through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values.
Line Segment 1: d = √(1 - 2)² + (4 - 8)² = 4.123
Line Segment 2: d = √(18 - 14)² + (12 - 1)² = 11.70
Dividing the answers will give us 0.352
