we are given
[tex] sin(\theta)=cos(73) [/tex]
we have to find theta
so, firstly we can write sin in terms of cos
[tex] sin(\theta)=cos(90-\theta) [/tex]
now, we can set it equal
[tex] cos(90-\theta)=cos(73) [/tex]
Since, both sides are cos
so, we can set angles equal
[tex] 90-\theta=73 [/tex]
now, we can solve for theta
we get
[tex] \theta=17 [/tex]..............Answer
