In triangle STU
And also the length of US is 15 feet
Since the right angle is U, then the hypotenuse is ST
Since SU is adjacent to < S, then we can use the cosine ratio
Adjacent is SU = 15
m< S = 25 degrees

Answer:
- a[1] = -80
- a[n] = -a[n-1]/4
Step-by-step explanation:
The first term is -80, so the first part of the recursive definition is ...
a[1] = -80
The common ratio is 20/-80 = -1/4, so the recursive rule is ...
a[n] = (-1/4)a[n-1]
Answer:
The answer is C. 168 in^2
Step-by-step explanation:
(Area = Base x Height)
21 * 8 = 168
➳This number can be written in scientific notation as 1.86 times a power of 10.
