7-18 are all in the same question, i tried but im getting them wrong and can't figure out why, please help!!

Use a calculator to find the values of \( x \). Enter decimals to the nearest 10th for sides and round to the nearest whole number for angles.

**Diagrams of Right Triangles:**

**7.**  
- Triangle with a known side of 8 and an angle of \( 40^\circ \).
- Unknown side labeled \( x \).

**8.**  
- Triangle with a known side of 9, and a hypotenuse of 14.
- Unknown angle labeled \( x^\circ \).

**9.**  
- Triangle with a side of 12, an angle of \( 57^\circ \), and an unknown side \( x \).

**10.**  
- Triangle with sides 18 and 16.
- Unknown angle labeled \( x^\circ \).

**11.**  
- Triangle with a side of 3 and an angle of \( 50^\circ \).
- Unknown side labeled \( x \).

**12.**  
- Triangle with sides 24 and 20.
- Unknown angle labeled \( x^\circ \).

**13.**  
- Triangle with a side of 16 and an angle of \( 34^\circ \).
- Unknown side labeled \( x \).

**14.**  
- Triangle with a side of 10 and a hypotenuse of 18.
- Unknown angle labeled \( x^\circ \).

**15.**  
- Triangle with a side of 23 and an angle of \( 42^\circ \).
- Unknown side labeled \( x \).

The image shows three right-angled triangles labeled as 16, 17, and 18.

**Triangle 16:**
- The sides are labeled as 2 (adjacent to angle \(x^\circ\)) and 1.5 (opposite angle \(x^\circ\)).
- There is a prompt for calculating the value of angle \(x^\circ\).

**Triangle 17:**
- The angle labeled is \(37^\circ\).
- The side opposite angle \(37^\circ\) is labeled \(x\).
- The adjacent side, to the right of the angle, measures 4 units.
- There’s a prompt for calculating the value of \(x\).

**Triangle 18:**
- The sides measure 38 and 36 units.
- The angle opposite the side measuring 36 units is labeled \(x^\circ\).
- There’s an area to input the value of \(x^\circ\).

Each triangle comes with placeholders where users are likely expected to input their answers for the corresponding angles or side lengths.
