Question

I really need these answered!

Answer 1

Explanation:

#1)
`\arcsin \left(0.64958\right)=0.70703\dots \quad \begin{pmatrix}\mathrm{Degrees:}&40.51^(\circ \:)\end{pmatrix}`

∡C =62.49

`(\left(\sin \left(27^(\circ \:)\right)\right))/(3)=(\sin \left(54^(\circ \:)\right))/(x)\quad :\quad x=(3\left(√(5)+1\right))/(\sin \left(27^(\circ \:)\right)\cdot \:4)\quad \left(\mathrm{Decimal}:\quad x=5.34603\dots \right)`
