Answer:
63°
Step-by-step explanation:
First, by looking at the angle we see that the overall angle is a right angle. This means that the total will add up to 90°.
Knowing this we can then subtract
90° - 27° = 63°
63
The measure of a right angle is always 90 so
90-27=63
The answer is -1 , because when you add a negative number to a positive number the negative number will subtract , and vise versa.
