Question

1. in this square, all the angles are equal. what is the measure of angle ( x^circ )?

Explanation:

Step1: Recall square interior angle

Each interior angle of a square is $90^\circ$.

Step2: Identify linear pair with $x$

The interior angle and $x$ form a straight line, so $x + 90^\circ = 180^\circ$.

Step3: Solve for $x$

$x = 180^\circ - 90^\circ$

Answer:

$90^\circ$
