Answer:
57 degrees! : D
Step-by-step explanation:
Every triangle angles(all of them) add up to 190 degrees.
so 33+x+90 degrees.
Why do we add 90 degrees? because there is a little "square on the bottom right explaining that it is a 90-degree angle.
so 33+90=123
so x=180(our original sum) minus 123
and so x=57 degrees
