Answer:
RS = 12.2 in ⇒ answer (a)
Step-by-step explanation:
∵ m∠R = 78° , m∠T = 39° , TS = 19
∵ By using sin Rule:
∵ ST/sin∠R = RS/sin∠T
∴ 19/sin78 = RS/sin39
∴ RS = (19 × sin39) ÷ sin 78 = 12.2 in ⇒ answer (a)
so first lets make the denominators the same so that we can divide
1/3 = 2/6
5/6
if you divide johny can make 2 cups of serving and R 1/5
