Step-by-step explanation:
Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
Answer:
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = km/min
Time taken up the hill = minutes
Speed of Wilmer down the hill = km/min
Time taken up the hill = minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
Distance up the hill =
Distance down the hill =
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
