Answer:
A
Step-by-step explanation:
given sin x ≈ 0.2588, then
x = (0.2588) ≈ 15°
using the cofunction identity
cos x = sin(90 - x)
the complement of 15° is 90° - 15° = 75°, hence
cos 75° = sin(90 - 75)° = sin15° ≈ 0.2588
Round the whole number to the given place. 75,801,300 to the nearest million

To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.
