Answer:
sin75°=sin(45°+30°)=(√6+√2)/4
Step-by-step explanation:
sin75°=sin(45°+30°)
=sin45°*cos30°+cos45°*sin30°
=(√2/2)* (√3/2)+ (√2/2)*(1/2)
=(√6+√2)/4
<em>sin75°=sin(45°+30°)=(√6+√2)/4</em>
<em>sin75°=sin(45°+30°)</em>

third and last choices
DPR and RPD
(4,2) and (2,-2)
using m=y2-y1/x2-x1
m= -2-2/2-4=-4/-2
therefore,
m=2
