Velocity, in km/hr is the x-axis.
Breaking distance "s" in meters is on the y-axis.
Each curved line represents the different road conditions.
for (a.) find the y-coordinate for each
Dry, curve A. follow the 50km/hr up to the curve and see it corresponds to about 30 m
Wet road, curve B. follow the 50km/hr mark up to see it corresponds to 80 m
Icey, curve T is 140 m
for (b.) they give you the breaking distance on the y-axis to find the corresponding speeds for each road condition. Follow the 60 m mark across to find each x-coordinate,.
Dry curve A, 70 km/hr
Wet curve B, about 45 km/hr
Icey curve T, 30 km/hr
The ASA postulate.
You can tell that in goes in that order with line XZ and AC where there is an angle, a side, and then another angle
Anthony has more as 47 x 4 is 188 which is higher than 173
X+4-4=15.25-4
X=11.25
Answer would be 1. X=11.25
