Ask the student a question, and give any hints about how they should answer this part.

Solve $\var{coeffsin}sin(x)=\var{RHS}$ between $0 \leq x<360^o$

Write your answers here with the smallest first and giving your answer to 3 significant figures.

$x=$ First solution $^o$ or Second solution $^o$

Advice

WORKED SOLUTIONS

$\begin{align} \var{coeffsin}sin{x} &=\var{RHS} \\\\ sin{x} &=\frac{\var{RHS}}{\var{coeffsin}} \\\\ x &=\arcsin{\frac{\var{RHS}}{\var{coeffsin}}} \\\\ x_1 &=\var{first_soln_3}^o \text { to 3 sig fig}\\\\ x_2 &=180-\var{first_soln_5}=\var{second_soln_3}^o\text { to 3 sig fig} \end{align}$
