14 is the best answer can i get brainliest?

When two lines intersect, they form two pairs of equal angles, which, taking one of each, add up to 180°. (jargon: angles forming a straight line   show more

the speed of the vehicle should be 57.68 ft/s Step-by-step explanation: Given: child is running ahead of vehicle by 65-70 ft. we are given with range of stopping distance The stopping distance is calculated by where μ = 0.8, coefficient of static friction g =  32ft/s² now, at  d = 65 ft. v = 7.155√(65) = 57.68 ft/s at  d = 70 ft. v = 7.155√(70) = 59.86 ft/s To be safe, the speed of the vehicle should be 57.68 ft/s
