now let's recall that a full circle has 360°, so then 1140 = 360 + 360 + 360 + 60.
namely, 1140 is 3 full-go-around the circle and then it lands on the I Quadrant at 60°. Thus cos(1140°) = cos(60°).
what's that cosine of 60°? Check the picture below.
Answer:
(-5, 2)
Step-by-step explanation:
Three corners of a rectangular city block are located at (2,2), (2,-4) and (-5,-4) on a coordinate plane. What are the coordinates of the fourth Coordinate?
Solution:
A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. Also, all the angles are at 90 degrees.
Since the city block is rectangular in shape, therefore the fourth coordinate would have the same y coordinate as the point (2, 2) and it would also have the same x coordinate as (-5, -4).
Hence the fourth coordinate is (-5, 2)
37 = 2/3x - 1
37 + 1 = 2/3x
38 = 2/3x
38 / (2/3) = x
38 * 3/2 = x
114/2 = x
57 = x <=== when complete, the highway will be 57 miles
