We know that : (a - b)(a + b) = a² - b²
We know that : 1 - sin²x = cos²x
We know that : sec²x = 1 + tan²x
1. m∠1 + m∠2 = 180°
2. Definition of bisector

4. Substitution Property of Equality
Answer:
5x + 2y + z
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of all the sides of the polygon. This polygons has 8 sides. Their lengths are:
x, x, x, x, x, y, y, z
The perimeter of the polygon is the sum of the lengths shown above.
perimeter = x + x + x + x + x + y + y + z
The expression above can be simplified by combining like terms.
perimeter = 5x + 2y + z
Answer: Farm Fresh
Explanation: Farm Fresh offers the lowest unit rate for lettuce, in dollars per pound. It after the lettuce at a lower price compared to the rest
Answer:
Step-by-step explanation:
The given figure is parallelogram becasue their opposite sides are equal.
68+45+30+x=180 degree (sum of adjacent sides of a parallelogram are equal)
143 +x=180
x=180-143
x=37 degree
y=45 degree
