Since k and j are parallel, angle 4 is equal to the angle to the left of 60 degrees. Since j is a line, the angle to the left of 60 added on to 60 is 180.
180 -60 = 120. The angle is 120 degrees.
Since angle 4 is equal to that angle, angle 4 is also 120 degrees.
For a Geometric sequence: a n = a ( n-1 ) * r In this case: a 1 = 30 a 2 = 30 * 1/2 = 15 a 3 = 15 * 1/2 = 7.5 a 4 = 7.5 * 1/2 = 3.75 = 3 3/4 Answer: The value of the fourth term is 3.75 or 3 3/4.
where the sign depends on the location of the terminal side of the angle. Since the terminal side lies in the fourth quadrant, that means the cosine of the angle is positive, so
Which polygons can be mapped onto each other similarity transformations? If you are talking about this image, the answer is; polygons 1 and 3. Correct me if I'm wrong.
