Find the measurements

Step-by-step explanation:
1) to calculate the measurement of Unlabeled angle:
180-90-27=63°;
2) to calculate the measurement of y:
180-51-63=66°
Answer:
y= 66
the angle that the arrow is pointing to = 63
Step-by-step explanation:
you can subtract 90 by 27 to get the angle measure that the arrow is 63
we know that all of the angles in a triangle are 180
so we can add up 51 and 63 to get 114
we subtract 180 by 114 to get 66
66 degrees
