Answer:
C.
Step-by-step explanation:
Can't be a or b slope is too small so its between c and d C. has the more accurate slope
42° and 48°
Complementary angles sum to 90°, hence
x + 10 + x + 4 = 90
2x + 14 = 90 ( subtract 14 from both sides )
2x = 76 ( divide both sides by 2 )
x = 38
x + 10 = 38 + 10 = 48° and x + 4 = 38 + 4 = 42°
r≈3.55%
try 36?
410 - 25 = 386
385 ÷ 55 = 7 passengers
