Answer: x=26 degrees
Explanation:
90+x+64=180 ==> A right angle, x, and 64 lie on a straight line. Straight lines add up to 180 degrees and are called straight angles. Right angles are denoted with a tiny square inside them and measure 90 degrees.
90-90+x+64=180-90
x+64=180-90
x+64=90
x+64-64=90-64
x=90-64
x=26 degrees
