First term: a(1) = 4; common ratio: r = 2
Then:
a(n) = 4(2)^(n-1)
Check: Predict the 4th term using this formula:
a(4) = 4(2)^3 = 4(8) = 32 (correct)
Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft
I hope this helps
Answer:
its 51
Step-by-step explanation:
