volume_mute

In the figure, quadrilateral RSTU is a rectangle with \(RS = 12\) ft and diagonal \(RT = 13\) ft. Find \(m(\angle SRU)\).

GRSTURS = 12 ftRT = 13 ft∠SRU = ?

Correct Answer

90°

Explanation

In any rectangle, all four angles are right angles. Therefore \(m(\angle SRU) = 90°\), regardless of the lengths of the sides or diagonals.
