Answer 1

`\begin{gathered} 5) \\ To\text{ calculate x} \\ \cos (37)=(x)/(12) \\ x=\text{ 12}\cdot\text{cos(37)}=9.58\approx10 \\ x=10 \\ the\text{ value of x is 10} \\ \\ 6) \\ To\text{ calculate x} \\ \sin \text{ (20)=}(16)/(x) \\ \\ x=\frac{16}{\sin\text{ (20)}}=46.78\approx47 \\ the\text{ value of x is 47} \\ \\ 7)\text{ } \\ To\text{ calculate x} \\ \cos (34)=(x)/(19) \\ \\ x=19\cdot\cos (34) \\ x=15.75\approx16 \\ x=16 \\ the\text{ value of x is 1}6 \\ \\ 8)\text{ } \\ To\text{ calculate x} \\ \tan (70)=(x)/(11) \\ \\ x=11\cdot\tan (70) \\ x=30.22\approx30 \\ x=30 \\ the\text{ value of x is 30} \end{gathered}`
