I think what's your trying to say is 419-200? If so it's 219
2/5 + 2/4 = 8/20 + 10/20 = 18/20 = 9/10
Translation, rotation, and reflection are always congruent. Dilation's are similar to each other....

Answer:
20
Step-by-step explanation:
straight line is 180 degrees
110+?=180
?=70
y=90 because it is a right angle
All angles of a right triangle added equals 180
so 70+90=160
180-160=20
x=20
