Answer:
Step-by-step explanation:
y and 76 are vertically opposite angles
x and z are vertically opposite angles
Linear pairs.
If sum of two adjacent angles are 180, then they are linear pair.
x & 76 are linear pairs
y & z are linear pairs
z & 76 are linear pairs
x and y are linear pairs
Solutions:
y = 76 { vertically opposite angles are equal}
x + 76 = 180 { linear pair}
x = 180 - 76
x = 104
z = x {Vertically opposite angles are equal}
z = 104
The cost to build a deck that is 25 feet by 20 feet is 1625
<h3>How to determine the cost?</h3>
The given parameters are:
Cost per square feet = 3.25
Dimensions = 25 feet by 20 feet
The cost to build the deck is calculated as
Cost = Cost per square feet * Product of dimensions
So, we have
Cost = 3.25 * 25 * 20
Evaluate
Cost = 1625
Hence, the cost to build a deck that is 25 feet by 20 feet is 1625
