The length of side AB is 8.856cm
To find the length of side AB in a triangle with angle C measuring 41° and side AC measuring 13.5 cm, we can use the trigonometric sine ratio. The sine ratio is defined as:
![\[ \sin(\theta) = \frac{\text{opposite side}}{\text{hypotenuse}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/q9anzgohtbhnzr7jhukvp7neuraublndf5.png)
In this case, side AB is the opposite side to angle C, and side AC is the hypotenuse. Therefore:
![\[ \sin(41°) = \frac{AB}{13.5 \, \text{cm}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/w1ks1icgh8muwbumrnwaohksq799y19ypt.png)
To find side AB, rearrange the equation:
![\[ AB = 13.5 \, \text{cm} * \sin(41°) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/izrrvnwj7ui6r1on2hgbux74n0rdn3qah6.png)
Now, plug in the values and calculate:
![\[ AB \approx 13.5 \, \text{cm} * \sin(41°) \]\\AB \approx 13.5 \, \text{cm} * 0.656059 \]\\AB \approx 8.85598 \, \text{cm} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/y9xgqbbreno33ak1jhu9y4ujmbkqui059j.png)
Rounding to three significant figures, the length of side AB is approximately
. The given answer of
is very close and might be rounded differently.
