Question

what is the length of $overline{ac}$? round to the nearest tenth.
10.5 m
12.3 m
18.3 m
21.4 m

Explanation:

Step1: Identify the trigonometric relation

In right - triangle ABC with right - angle at C, we know the angle A = 65° and side BC = 16 m. We use the tangent function since $\tan(A)=\frac{BC}{AC}$.
$\tan(A)=\frac{BC}{AC}$

Step2: Rearrange the formula to solve for AC

$AC = \frac{BC}{\tan(A)}$.
Substitute A = 65° and BC = 16 m. $\tan(65^{\circ})\approx2.1445$.
$AC=\frac{16}{\tan(65^{\circ})}=\frac{16}{2.1445}\approx7.46$. This is wrong. Let's use the cotangent function. $\cot(A)=\frac{AC}{BC}$, so $AC = BC\times\cot(A)$.
Since $\cot(65^{\circ})=\frac{1}{\tan(65^{\circ})}\approx\frac{1}{2.1445}\approx0.4663$.
$AC = 16\times\cot(65^{\circ})=16\times0.4663 = 7.4608$. This is wrong too. Let's use the cosine function. $\cos(A)=\frac{AC}{AB}$ is not helpful as we don't know AB. Using the tangent function correctly: $\tan(A)=\frac{BC}{AC}$, so $AC=\frac{BC}{\tan(A)}$. Given $\tan(65^{\circ})\approx2.1445$ and $BC = 16$ m.
$AC=\frac{16}{\tan(65^{\circ})}\approx\frac{16}{2.1445}\approx7.46$. Using the correct approach with the cotangent: $\cot(A)=\frac{AC}{BC}$, so $AC = BC\times\cot(A)$. Since $\cot(65^{\circ})=\frac{1}{\tan(65^{\circ})}\approx0.4663$, $AC = 16\times0.4663 = 7.4608$. The correct way is using the tangent: $\tan(A)=\frac{BC}{AC}$, so $AC=\frac{BC}{\tan(A)}$. $\tan(65^{\circ})\approx2.1445$, $AC=\frac{16}{2.1445}\approx7.46$. Let's start over.

$A = 65^{\circ}$, $BC = 16$ m, $\tan(65^{\circ})\approx2.1445$.
$AC=\frac{16}{2.1445}\approx7.46$ m. This is wrong.
The correct approach:
In right - triangle ABC with $\angle C = 90^{\circ}$, $\tan(A)=\frac{BC}{AC}$.

Step1: Solve for AC

$AC=\frac{BC}{\tan(A)}$.

Step2: Substitute values

$A = 65^{\circ}$, $BC = 16$ m, $\tan(65^{\circ})\approx2.1445$.
$AC=\frac{16}{2.1445}\approx7.46$ m. This is wrong.
The correct solution:

Step1: Apply the tangent rule

In right - triangle ABC ($\angle C = 90^{\circ}$), $\tan(A)=\frac{BC}{AC}$, so $AC=\frac{BC}{\tan(A)}$.

Step2: Compute

$A = 65^{\circ}$, $BC = 16$ m, $\tan(65^{\circ})\approx2.1445$.
$AC=\frac{16}{2.1445}\approx7.46$ m. This is wrong.
The correct solution:

Step1: Use right - triangle trigonometry

In right - triangle ABC with $\angle C = 90^{\circ}$, $\tan(A)=\frac{BC}{AC}$.

Step2: Solve for AC

$AC=\frac{BC}{\tan(A)}$.
