First choose 1 equation and set it equal to 180 because supplementary angles equal up to 180 degrees.
12q - 9 =180
Now solve for q.
12q - 9 +9 = 180 + 9
12q = 189
12q/12 = 18912
q = 15.75
now subtract 15.75 from 180
180.00 - 15.75 = 164.25
Your angles equal to 164.25 and 15.75 degrees.
Answer:
16 feet
The length and the feet long are the same thing in this situation.
So, x + y = 42 and y - x = 5;
Then, y = x + 5;
Finally, x + x + 5 = 42;
2x + 5 = 42;
2x = 37;
x = 18.5;
y = 18.5 + 5;
y = 23.5;
Answer: B?
Step-by-step explanation:
Since it already shows it in feet, you can multiply 18 by 16.
-288
And because it is $4.50 per square root, you can multiply 4.50 by 288 and you get 1,296.
