Question
Find the values of : $2 \sin 30^{\circ}+\cos 0^{\circ}+3 \sin 90^{\circ}$
✓
Answer
$2 \sin 30^{\circ}+\cos 0^{\circ}+3 \sin 90^{\circ}$
$2 \sin 30^{\circ}+\cos 0^{\circ}+3 \sin 90^{\circ}=2\left(\frac{1}{2}\right)+1+3(1)$
$=1+1+3$
$\therefore 2 \sin 30^{\circ}+\cos 0^{\circ}+3 \sin 90^{\circ}=5$
$2 \sin 30^{\circ}+\cos 0^{\circ}+3 \sin 90^{\circ}=2\left(\frac{1}{2}\right)+1+3(1)$
$=1+1+3$
$\therefore 2 \sin 30^{\circ}+\cos 0^{\circ}+3 \sin 90^{\circ}=5$
