Question

Find x in the rectangle below

Answer 1

• 25°

---------------------

In the triangle TQU we have:

• Sides TQ and QU are equal since diagonals of a rectangle are congruent and bisect each other.
• Sides TQ and QU are opposite to angles with measure of 25° and x.

It means ΔTOU is isosceles and therefore:

• x = 25°
