For this case we have that by definition of trigonometric relations of rectangular triangles, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. So:

Where h is the hypotenuse.

We cleared h:

We rationalize:

ANswer:
Option A
Picturing the tent helps, but we can actually solve this question using simple algebra and no knowledge of triangles.
The key is this function:
(b/h) = 2/√3
We want to get h by itself. First, multiply both sides by h:
b = h(2/√3) Now multiply both sides by the reciprical, (√3/2)
(√3/2) b = h
Therefore, the answer is C) h= b(√3/2)
Answer:

Step-by-step explanation:



= 2a - 1
2(
) = 2(2a - 1) <em>multiplied both sides by 2 </em>
ab = 4a - 2 <em>distributed the 2 on the right side</em>
ab - 4a = -2 <em>subtracted 4a from both sides</em>
a(b - 4) = -2 factored out "a" from the left side
a =
<em>divided (b - 4) on both sides</em>
Answer: a =
Answer:
$2400
Step-by-step explanation:
as you realize, it is going down by $400 per year
6000, 5600, 5200, 4800, 4400, 4000, 3600, 3200, 2800, 2400
1. 2. 3. 4. 5. 6. 7. 8. 9. 10
it would be $2400
