Question

3. The complement of 80 degree
A) 100 degree
B) 180 degree
C) zero
D)10 degree​

Answer 1

Answer:

Option D: 10 degree

Step-by-step explanation:

When two angles are added and the answer comes as 90 degree, then it means that the both angles are complementary to each other.

For example,

here it is given that,

One of the angles is 80 degree. So, the complement of 80 degree would be:

90-80=10 degree.

OR,

You could also consider the other angle to be x.

So the equation formed is:

x + 80 = 90

OR x = 90 - 80 = 10.
