The answer is $1.20$ $1.20$

Explanation:

${sin 45}^{o} = 0.71$ $sin45^"o"=0.71$
${cos 60}^{o} = 0.50$ $cos60^"o"=0.50$

$0.71 + 0.50 = 1.20$ $0.71+0.50=1.20$

$\frac{1 + \sqrt{2}}{2}$ $(1+sqrt(2))/2$

Explanation:

assuming the values are in degrees,
$sin (45) = sin (\frac{π}{4}) = \frac{\sqrt{2}}{2}$ $sin(45)=sin(pi/4)=sqrt(2)/2$
$cos (60) = cos (\frac{π}{3}) = \frac{1}{2}$ $cos(60)=cos(pi/3)=1/2$
so
$sin (45) + cos (60) = \frac{\sqrt{2}}{2} + \frac{1}{2}$ $sin(45)+cos(60)=sqrt(2)/2 + 1/2$
$= \frac{1 + \sqrt{2}}{2}$ $=(1+sqrt(2))/2$
