Find side x, giving your answer to 1 decimal place.<br> 810<br> 7 cm<br> 40°<br> Х
Andru [333]

Answer:

10.8

Step-by-step explanation:

By sine rule:

\frac{x}{ \sin 81 \degree}  =  \frac{7}{ \sin 40 \degree}  \\  \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree}   \\  \\ x =  \frac{7 \times0.9876883406 }{0.6427876097}  \\  \\ x =  \frac{6.91381838}{0.6427876097}  \\  \\ x = 10.755992 \\  \\ x  \approx 10.8
