Answer:
D. 36 units
Step-by-step explanation:
The description of the triangle is:
<em>triangle XYW in which angle W is a right angle, angle X measure f degrees, and angle Y measures d degrees
</em>
Therefore, side XY is adjacent to f and side XY is the hypotenuse
From definition:
cos(f) = adjacent/hypotenuse
Replacing:
cos(f) = XW/XY
4/9 = 16/XY
XY = 16*9/4
XY = 36 units
Answer:yea its 3
Step-by-step explanation:
Y=kx is the direct variation equation
First plug in the x, y values given to find K
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation.
y=3.6x
Plug in the x value to solve for y.
y = 3.6(11)
y= 39.6
