You would begin by choosing which trigonometric function to use.
In this case, you would use sine.
Sine is opposite over hypotenuse.
Opposite of the 35 degree angle is 18, and you want to find the hypotenuse which is x.
sin(35) =
(multiply x to both sides)
x sin(35) = 18 (divide sin(35) to both sides)
x = 31.38204...
So, therefore x = 31.38. I don't know what decimal point you're supposed to round to, so I'm gonna guess the hundredths place. :)

Answer:
; minimum
Step-by-step explanation:
Given:
The function is,
The given function represent a parabola and can be expressed in vertex form as:
The vertex form of a parabola is , where,
is the vertex.
So, the vertex is .
In order to graph the given parabola, we find some points on it.
Let
So, the points are .
Mark these points on the graph and join them using a smooth curve.
The graph is shown below.
From the graph, we conclude that at the vertex , it is minimum.
