First you need to know the definition of a complementary angle. That means that two angles add up to 90 degrees, or a right angle.
To find an angle complementary to a 78 degree angle, you need to subtract 78 from 90.
90 - 78 = 12
The answer would be 8. hope this helps
You need to write it out such as number 8 would be 10x10x10x10 so for every number on top you multiply the number by itself
Move the decimal to the right twice to make this into a percent:
1.03 —-> 103%
