Answer:
x = 7
Step-by-step explanation:
Alternate interior angles are equal. Alternate interior angles look like these two angles.
7x - 7 = 4x + 14 Add 7 to both sides
7x - 7 + 7 = 4x + 14+7 Combine
7x = 4x + 21 Subract 4x from both sides
7x-4x = 4x - 4x + 21 Combine
3x = 21 Divide by 3
3x/3 = 21/3 Do the division
x = 7
Answer:
x=7
Step-by-step explanation:
Equate the angles 7x-7 and 4x+14 and solve:
7x-7 = 4x+14
7x-4x = 14+7
3x = 21
x = 7

You just have to add them together because that is perimeter.
Plug the value of x in the equation
2(6 - y) = 8
12 - 2y = 8
-2y = -4
y = 2
