This a pretty typical right triangle trig problem; the first step is to figure out what we have and what we want in relation to an acute angle in the problem.
Here we have a right triangle, G=90°, and we're given angle F=23°. So we have to name everything in relation to F.
31 = FG is <em>adjacent </em>to F.
x = GE is <em>opposite </em>to F.
OK, we have an opposite and adjacent; that tells us we need to use the tangent of F. Let's write it:
tan 23° = tan F = opp/adj = x/31
Solving,
x = 31 tan 23°
I hate the calculator part. I used to love that part.
x = 31 tan 23° ≈ 13.16 feet
Answer: 4) x ≈ 13.2 ft
Annual interest - 4%
interest in 1 year
(4/100) * 4000
160
interest in 10 years
160 * 10
1600
So the amount you have at the end of 10 years
4000 + 1600
$ 5600
Answer: Yes, The relation is a function, they are the exact opposite.
Step-by-step explanation:
It is 800 because the 4 can not tell the what to do so that it is
