Find Hypotenuse 938B18
1. **State the problem:** We have a right triangle GHI with a right angle at H. Side GH is 5.6 units, angle at I is 29°, and GI is the hypotenuse labeled $x$. We need to find $x$.
2. **Identify the sides relative to angle I:**
- GH is opposite angle I.
- HI is adjacent to angle I.
- GI is the hypotenuse.
3. **Use the sine function:**
Since sine relates the opposite side to the hypotenuse, we use:
$$\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}$$
Here, $\theta = 29^\circ$, opposite side = 5.6, hypotenuse = $x$.
4. **Set up the equation:**
$$\sin(29^\circ) = \frac{5.6}{x}$$
5. **Solve for $x$:**
$$x = \frac{5.6}{\sin(29^\circ)}$$
6. **Calculate $\sin(29^\circ)$:**
$$\sin(29^\circ) \approx 0.4848$$
7. **Find $x$:**
$$x = \frac{5.6}{0.4848} \approx 11.55$$
8. **Round to the nearest tenth:**
$$x \approx 11.6$$
**Final answer:** $x = 11.6$
