Particular sound wave can be graphed using the function y = 1 sin 2x . find the amplitude of the function.

What is the measure of the smallest angle in the diagram? 15 29 32 45

Which shows the graph of the solution set of 3y – 2x > –18?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
