Verified answer

$\frac{sin36+sin40+cos62+cos42}{ 4 cos6*cos4*sin38} = \\\\
\frac{sin36+sin40+sin28+sin48}{4sin84*sin86*sin38} = \\\\ 
\frac{2sin38*cos2+2sin38*cos10}{4sin84*sin86*sin38} = \\\\
\frac{cos2+cos10}{2sin84*sin86} = \\\\
\frac{2cos6*cos4}{2sin84*sin86} = \frac{2sin84*sin86}{2sin84*sin86} = 1$
