Can you use tables, a calculator or a power series?
The answer is 162.5 degrees.
17.46 degrees (0.3047 radians) has the same sine, and one could use the expansion
sin x = x - x^3/6 + x^5/120 +...
to show that sin 0.3047 = 0.3
Solve the equation sinθ=0.3 to the nearest tenth. Use the restrictions 90°≤θ≤180°.
