The angles are congruent because they are vertical so we can set them equal to one another.
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
Answer:
htp(
Step-by-step explanation:
Part A If the polygon is above the line, the rotation angle is 180+a.
If the polygon is below the line, the rotation is a.
Part B Rotations may be clockwise or counterclockwise. When working in the coordinate plane: assume the center of rotation to be the origin unless told otherwise. assume a positive angle of rotation turns the figure counterclockwise, and a negative angle turns the figure
Answer: 1 and 2/4 of ribbon
Step-by-step explanation:
Answer: The points are, the top left one, (21,3) and the one on the bottom is (6, 12)
Step-by-step explanation: For the slope, we label one of the points, with y or x. For example, (21, 3) we would label 21 either y1 or x1. Say we put y2, then 3 would be x2. Moving on, (6,12) this time we could label 6 as either y1 or x1. Same thing, but this time we are going to label 6 as y1 and 12 x1. Again, it’s DOES NOT matter what you label them as.
Now to solve it, remember y numbers always go on top! M which is slope. M = y2 - y 1 / x2 - x 1 or with the numbers M = 21 - 6 / 12 - 3 = 15/9 simplified = 5/3
