Sin < O = 10/15 = 2/3
so m < O = 41.8 degrees
m < Y = 90 - 41.8 = 48.2 degrees
Answer:
C
Step-by-step explanation:
BC its backwards den the 1+3x
Answer: 100
Step-by-step explanation:
T1 + t2 = 2h and 30min;
t1 * 600 = t2 * 400 => t2 = (3/2) * t1;
then, t1 + (3/2) * t1 = 2h and 30min => 2t1 + 3t1 = 5h => 5*t1 = 5h => t1 = 1h => t2 = 1h and 30 min;
The distance is 2 * 1 * 600 = 1200miles;
