To find the height of the canvas, we can use trigonometric functions. Given that the diagonal of the canvas is 23.3 inches and it forms a 31° angle with the bottom of the canvas, we can use the sine function:
\[
\text{Height} = \text{Diagonal} \times \sin(\theta)
\]
Where:
- \(\theta\) is the angle (31°),
- Diagonal = 23.3 inches.
So, we calculate:
\[
\text{Height} = 23.3 \times \sin(31^\circ)
\]
First, we need to find \(\sin(31^\circ)\). Using a calculator:
\(\sin(31°) \approx 0.5150\).
Now, substitute back into the height equation:
\[
\text{Height} = 23.3 \times 0.5150 \approx 12.00 \text{ inches}
\]
Now we round to the nearest inch. Thus, the height of the canvas is approximately **12 inches**.
\[
