Answer: C
Explanation:
Since tan(H) equals 1, we can conclude that angle H equals 45 degrees. Therefore, we know that it is a 45-45-90 triangle. Therefore, since both legs are equal, sin or cos doesn’t matter. Therefore, C is correct. (Draw it for yourself, it helps)
Answer:
the average velocity is 86 km/h for the trip
Step-by-step explanation:
from the definition of average velocity
average velocity = distance covered / time required = 1682 km /(19 h + 28 min/60 min/h) = 86 km/h
therefore the average velocity is 86 km/h for the trip
