Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36

hi <3
so basically, there are a few rules you need to know of and i'll describe those first.
angles in a triangle sum to 180 degrees. AND
angles on a straight line sum to 180 degrees
so, by using the first rule, we can calculate the missing angle within the triangle:
180 - (52 + 90) = 38
now, we can use the second rule to find x
180 - 38 = 142
x = 142 degrees
hope this helps :)
