Answer:
Yeah
Step-by-step explanation:
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
40 is your answer. Because, you need the lowest multiple so we have to find it by making out a chart of their multiples
8, 16,24,32,40
10,20,30,40
The first same multiple they make is 40
