Answer:
<em>y = 12.3 cm</em>
Step-by-step explanation:
This is a right triangle, so we can use sin,cos, or tan to solve this.
First, with respect to the angle 35 degrees, we can say "y" is the "adjacent side".
Also, the hypotenuse is given as 15.
<em>Which trig ratio relates adjacent and hypotenuse? That is COS. So we can write and solve the equation below:</em>

<em>y = 12.3 cm</em>
Answer:
Option 3. f(x) is g(x) stretched vertically by a factor 8 and reflected about the x axis.
Step-by-step explanation:
The given functions are ----(1)
and g(x) = 4sin5x ------(2)
In the function (1)
Amplitude A =
In the function (2)
g(x) = 4sin5x Amplitude A' = 4
So when we compare these graphs we get
A' = 8A
Since the Graph number (2) is of positive sign that means Graph (1) is reflected about the x axis to get (2)
Therefore Option 3 is correct f(x) is stretched vertically by a factor of 8 and reflected by X axis
Answer:
57.6159 round if needed
Step-by-step explanation:
We know the length of the triangle which is 298. We know the base of the triangle which is 189.
We need to find angle of elevation so we must use tangent function.
Use inverse tan function
Round if needed.
