Answer: 30.01 feet.

Step-by-step explanation:

You need to remember this identity:

$tan\alpha=\frac{opposite}{adjacent}$

Observe the figure attached, where $h_t$ is the height in feet of the tree.

You need to calculate $h_1$ of the Triangle 1, where:

$\alpha= \alpha_1=42\°\\opposite=h_1\\adjacent=20$

Substitute values into $tan\alpha=\frac{opposite}{adjacent}$ and solve for $h_1$ :

$tan(42\°)=\frac{h_1}{20}\\\\h_1=20*tan(42\°)\\h_1=18$

Now you need to calculate $h_2$ of the Triangle 2, where:

$\alpha= \alpha_2=31\°\\opposite=h_2\\adjacent=20$

Substitute values into $tan\alpha=\frac{opposite}{adjacent}$ and solve for $h_2$ :

$tan(31\°)=\frac{h_2}{20}\\\\h_2=20*tan(31\°)\\h_2=12.01$

Then the height in feet of the tree is:

$h_t=h_1+h_2\\h_t=(18+12.01)ft\\h_t=30.01ft$

Answer:

Step-by-step explanation:

The absolute value always returns a positive value, that is

| - a | = | a | = a, thus

| 3 $\frac{1}{2}$ | = 3 $\frac{1}{2}$ → C
