How do i find the measure of each angle for tan B = 0.6000

use inverse tangent function:

 

find the complement and supplement of an angle with the given measure. a.)10° 10' 30" , b.)1° 40' 19"

a)
90°=89° 59' 60"
so...
complement:
89° 59' 60"-10° 10' 30"=
79° 49' 30"
supplement:
169° 49' 30"
b)
complement
89° 59' 60"-1° 40' 19"=
88° 19' 41"
supplement:
178° 19' 41"

An angle is one third of it's complement. What is the measure of the angle?

angle:x
complement:y
so that x+y=90
An angle is one third of it's complement means x=y/3 



so y=3x 

x+3x=90 

4x=90 
x=22.5

Convert 15(degrees) to radians
