In a right triangle, the tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side. In your triangle:
- Angle C is 26 degrees.
- Side BC (the opposite side to angle C) is 15.
- Side AB (the adjacent side to angle C) is what we are trying to find.
Using the tangent ratio:
\[
\tan(C) = \frac{\text{opposite}}{\text{adjacent}}
\]
Substituting the known values:
\[
\tan(26^\circ) = \frac{BC}{AB}
\]
This simplifies to:
\[
\tan(26^\circ) = \frac{15}{AB}
\]
Now, we can rearrange this equation to solve for \( AB \):
\[
AB = \frac{15}{\tan(26^\circ)}
\]
Next, we need to calculate \( \tan(26^\circ) \). Using a calculator, we find:
\[
\tan(26^\circ) \approx 0.4877
\]
Now substitute this value back into the equation:
\[
AB = \frac{15}{0.4877} \approx 30.73
\]
Rounding to the nearest hundredths, the length of side AB is:
\[
\boxed{30.73}
\]
- Angle C is 26 degrees.
- Side BC (the opposite side to angle C) is 15.
- Side AB (the adjacent side to angle C) is what we are trying to find.
Using the tangent ratio:
\[
\tan(C) = \frac{\text{opposite}}{\text{adjacent}}
\]
Substituting the known values:
\[
\tan(26^\circ) = \frac{BC}{AB}
\]
This simplifies to:
\[
\tan(26^\circ) = \frac{15}{AB}
\]
Now, we can rearrange this equation to solve for \( AB \):
\[
AB = \frac{15}{\tan(26^\circ)}
\]
Next, we need to calculate \( \tan(26^\circ) \). Using a calculator, we find:
\[
\tan(26^\circ) \approx 0.4877
\]
Now substitute this value back into the equation:
\[

\[

I apologize for any confusion. Let's go through the calculations step-by-step to ensure accuracy.
### Given:
- Angle \( C = 26^\circ \)
- Side \( BC \) (opposite side) = 15
- Side \( AB \) (adjacent side) = ?
### Using the Tangent Ratio:
The tangent of angle \( C \) is defined as:
\[
\tan(C) = \frac{\text{opposite}}{\text{adjacent}} = \frac{BC}{AB}
\]
Plugging in the values we have:
\[
\tan(26^\circ) = \frac{15}{AB}
\]
### Rearranging to find \( AB \):
\[
AB \cdot \tan(26^\circ) = 15
\]
\[
AB = \frac{15}{\tan(26^\circ)}
\]
### Calculating \( \tan(26^\circ) \):
Using a calculator, we find:
\[
\tan(26^\circ) \approx 0.4877
\]
### Calculate \( AB \):
\[
AB = \frac{15}{0.4877} \approx 30.73
\]
However, if you believe this is incorrect, I think there may have been a misunderstanding about which side is opposite and which is adjacent.
### Re-examining \( BC \):
If \( BC \) is the adjacent side and we are trying to find \( AB \) as the opposite side, we should set it up like this:
1. If \( AB \) is the opposite side, and \( BC \) is actually adjacent, the equation would be:
\[
\tan(26^\circ) = \frac{AB}{15}
\]
Rearranging gives:
\[
AB = 15 \cdot \tan(26^\circ)
\]
Now, calculating this correctly:
\[
AB = 15 \cdot \tan(26^\circ) \approx 15 \cdot 0.4877 \approx 7.31
\]
### Final Answer:
So if we are solving for the side opposite to the 26-degree angle \( (AB) \):
\[
AB \approx 7.31
\]
Rounded to the nearest hundredths, the correct length of side \( AB \) is:
\[
\boxed{7.31}
\]
If the configuration was intended differently, please provide more context or corrections. Thank you for your patience!
