Sin(theta) = opposite/hypotenuse
Sin(41 deg) = 2.5/x
Xsin(41) = 2.5
X = 2.5/sin(41)
X = 3.8
There will be seven spaces between the 1st and the 8th post.
The distance between posts is 20 meters
The distance between the 1st and the 8th post is 20×7 = 140 metres
Answer:
Step-by-step explanation:
The given function is
Which can be rewritten also as
We want to find the values of x for which
In order to do that, we just substitute -12 into f(x), and we solve the equation for x:
on the very far left it says (5,-1.5)
