If cos(-ϴ)=0.95, find sin(π/2-ϴ)

Furkat [3]

$\bf \textit{Cofunction Identities}
\\\\
sin\left(\frac{\pi}{2}-\theta\right)=cos(\theta)
\qquad 
cos\left(\frac{\pi}{2}-\theta\right)=sin(\theta)
\\\\\\
\stackrel{\textit{symmetry identities}}{cos(-\theta )=cos(\theta )}\\\\
-------------------------------\\\\
sin\left(\frac{\pi}{2}-\theta\right)=cos(\theta)=cos(-\theta )=0.95$

Kazeer [188]

Answer:

$40.25$ inches

Step-by-step explanation:

"pablo is as half as tall as eric"

$pablo=\frac{Eric}{2}$

$pablo=\frac{70in}{2}=35in$

and "annette is 5.25 inches taller than pablo"

$annete=pablo+5.25in$

$annette=35in+5.25in =40.45in$

Annette is 40.25 inches tall
