Question

Order the sides of the triangle from greatest to least.S60°R57°T

Answer 1

Since the sum of the interior angles of a triangle is 180°, we can easily find angle R:

`\begin{gathered} \measuredangle R+60+57=180 \\ \Rightarrow\measuredangle R=180-60-57=603 \\ \measuredangle R=63 \end{gathered}`
