Answer:

29 degrees to nearest degree.

Step-by-step explanation:

This is the angle whose tangent is  10/18 or 5/9.

this = 29 degrees

29°

Consider the right triangle between the plank and the ground

the angle can be found using tangent ratio

tanx° = \frac{opposite}{adjacent}

where adjacent = 18 and opposite = 10

tanx° = \frac{10}{18}

x = tan^{-1}(\frac{10}{18}) = 29.0546 ≈ 29°

If f(x) varies directly with x and f(x) = 72 when x = 6, find the value of f(x) when x = 3.
Levart [38]

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
