Answer:
x =104
y=76
z=104
Step-by-step explanation:
Y and 76 are vertical angles and vertical angles are equal
y = 76
x and 76 form a linear pair and linear pairs add to 180
x+76 = 180
x = 180-76
x = 104
x and z are vertical angles and vertical angles are equal
z = 104
Answer:
3rd option
Step-by-step explanation:
For the first question, we can extend all of the lines on the trapezoid, and triple the distance from B on the line, so we can use the fact that B is (2, 2), A is (0, 0), C is (4, 2), and D is (6, 0) to get that the new coordinates are A (-4, -4), B (2, 2), C (8, 2), and D (14, -4).
For the second question, notice that we are changing the size on the same line, and every side length is tripled by 3. If every side length is tripled by 3, then the perimeter of the new image is triple the perimeter of the original.
6 wore blue + 5 wore green + 3 wore black = 14
If there are a total of 18 total students, then the number of people who wore other colored shirts is 4 because 18-14= 4. Therefore, 4/14, which is 2/7 simplified, represents the students who did not wear blue, green or black.
