Answer:
The measures of angle y is 30 °.
Explanation:
We know that, the sum of two side of right angle is 90 °.
60 ° + y = 90 °
subtract 60 ° from each side
y = 90 ° - 60
y = 30 °
Therefore, the measures of angle y is 30°.
y = 27
The sum of the two angles is a right angle, which is 90 degrees
y+63 = 90
y = 90-63
y =27
