Solution
Which is the shortest side of the triangle?
Find the missing angle.
The sum of angles in a triangle is 180°. We are given two angles, 35° and 125°. Let the third angle be \(x\).
\(35 + 125 + x = 180\)
\(160 + x = 180\)
\(x = 180 - 160\)
\(x = 20\)
So, the third angle is 20°.
Relate the side lengths to the angles.
The shortest side is opposite the smallest angle.
The smallest angle is 20° which is at vertex A.
The side opposite to A is BC.
Therefore, BC is the shortest side.
