Answer
The longest side is 2.
the side opposite 60° is $\sqrt 3$.
Work Step by Step
The longest side of a 30°–60°–90° triangle is twice the shortest side and the side opposite the 60° angle is $\sqrt 3$ times the shortest side.
Given that
Shortest side = 1
Therefore
Longest side = 2 $\times $ shortest side = 2$\times$1 = 2
Side opposite 60° = $\sqrt 3\times $ shortest side = $\sqrt 3 \times$1 = $\sqrt 3$
