Answer:
U=(x+3) and V=7
Step-by-step explanation:
Hello!
First you have to count how many tallies the car went 9 tallies
Multiply the amount of tallies by how far they represent
9 * 0.8 = 7.2 meters
The car when 7.2 meters in half a second so we double this to get how fast it was going a second
7.2 * 2 = 14.4
The answer is 14.4 m/s
Hope this helps!
By law of the sine we have:
sine (y) /35.2=sine (95) / 86
Clearing we have:
sine (y) = (sine (95) / 86) * (35.2)
y = asine ((sine (95) / 86) * (35.2))
y = 24.0632456
Rounding:
y = 24 degrees
Answer:
The answer for this case is given by:
y = 24 degrees
