Question

Given the diagram below, what is sin (30°)?60°2.530°HTriangle not drawn to scaleOA.A.314B. 2O C.O D.

Answer 1

Case: Right-angle triangle

Method:

`\begin{gathered} Using\text{ }the\text{ }rule:1-√(3)-2 \\ \sin(30\degree)=(Opp)/(Hyp) \\ Hyp=2(2.5) \\ Hyp=5 \\ sin(30\degree)=(2.5)/(50) \end{gathered}`

Final answer:

`\begin{gathered} \\ sin(30\degree)=(1)/(2) \end{gathered}`
