Answer:
x=54
Step-by-step explanation:
these two angles are supplementary to each other. this is because alternate interior angles are congruent, and 2x+42 degrees is supplementary to the alternate interior angle of x-24 degrees. so, we can add these two numbers up and set it equal to 180.
2x+42+x-24=180
3x+18=180
3x=162
x=54
if this question is asking for x, 54 is the answer. if it is asking for the angle measures, plug in 54 for x for each angle and solve.
Pool and deck = 60 ft by 50 ft
First question: Area of the deck including the deck
A = 60*50 = 3000 ft^2
Average cost = $4,560
Discount offered = 20%
Second question: Cost after discount
This is a question of proportionality. That is;
$4,560 ------------ 100%
Actual cost ------ (100-20)% -----80%
Then,
Actual cost after discount = (4,560*80)/100 = $3,648
Area of the pool is 750 ft^2 and one side is 30 ft.
Third question: Length of the other side
Area = L*W, if Length, L = 30 ft, Width, W = ??
750 = 30*W
W = 750/30 = 25 ft.
Then, the other side is 25 ft long.
Cost per 10 ft length of fence costs $25.50
Fourth question: Total cost of fencing
Circumference = 2(L+W) = 2(60+50) = 220 ft
Number of 10 ft sections = Circumference/10 = 220/10 = 22 sections
Total cost = number of sections*Cost per section = 22*25.50 = $561
It’s is C. 3 because it makes sense
