Answer:
a = 60
b = 60
Step-by-step explanation:
We know that BC is 90°, because of the square thingy.
YB is 30°.
Now we do 180 - 30 - 90 = 60 (180 is the straight angle)
60 = b
Then a is the same.
6 ft equals 72 inches or 1.829 meters
Answer:18
Step-by-step explanation:
Note: Mathematicians start counting at 1, so by convention, n=1 is the first term. So we must define what the first term is. Then we have to figure out and include the common difference.
Taking a look at the examples again,
Sequence: 1, 2, 3, 4, … | Formula: a(n) = n + 1 | Recursive formula: a(n) = a(n-1) + 1, a(1) = 1
Sequence: 3, 8, 13, 18, … |Formula: b(n) = 5n - 2 | Recursive formula: b(n) = b(n-1) + 5, b(1) = 3
The area of the wall including the windows is 152ft
