Question 248959
Find the complement of an angle whose measure is pie/10.
How would I go about solving this. It is is radians right?


Yes, the angle is in radians.

Two angles are complementary if their sum = pi/2 (equivalent to 90 degrees).
So, in this case the complement x of pi/10 can be found by:

x + pi/10 = pi/2
x = pi/2 - pi/10
x ~ 3.14/2 - 3.14/10 

Calculate x.
