Question

sin 90 degree + Cos 60 degree + cos 45 degree x sin 30 degree minus Cos 0 degree + cos 45 degree

Answer 1

HOPE IT HELPS YOU.......

Answer 2

sin 90 + cos 60 + (cos 45 × sin 30) - cos 0+ cos 45

$1 + \frac{1}{2} + (\frac{1}{ \sqrt{2} } \times \frac{ 1 }{2} ) - 1 + \frac{1}{ \sqrt{2} }$

=

$\frac{1}{2 } + \frac{ 1}{2 \sqrt{2} } + \frac{1}{ \sqrt{2} }$

$\frac{ \sqrt{2 } + 1 + 2 }{2 \sqrt{2} }$

hope it helps you
