Answer:
9
Step-by-step explanation:
triangles always = 180 degrees
we know there is a 90 degree angle so 180-90=90
we know the other angle is 20 degrees so you do 90-20 which equals 70
now we know that the angle with x equals 70
so then you do 70-16 which equals 54
now just divide 54 by 6 and you get 9
so x=9
