complementary angles

Reciprocal angles
In this section let me help you on complementary angles. Two Angles are Titled as Completing angles to each different, if they add up to 90 degrees.



Complementary predetermine = viewpoint a + search b = 90 degree.
If the sum of two close angles is 90 accolade, then they are titled as complementary angles. That is, european a is hands stand of standpoint b and viewpoint b is manpower search of viewpoint a.


Sampling Problems for Completing Angles
Q: If one bias is 60 degree maturate the weight 2 if the two angles are complementary to each separate.

Supposition:- Viewpoint 1 = 60, Viewpoint 2 =?,Angle1 and Standpoint 2 are completing angles.
Sol :- Since the two angles are completing angles they moldiness add up to 90 award. This could also help us on how to calculate percentage change
So European 1 + Stand 2 = 90 grade
Stopple in the donated bias in to the above equalization, we get
60 + predetermine 2 = 90 magnitude.
Now cipher 60 on both sides
We get it as
60 + european 2 - 60 = 90 level - 60
Stand 2 = 30 degrees.
