Two plane mirrors form a 70° angle. for what angle x is the final ray horizontal?

I believe that the answer to the question provided above is angle x is the final ray horizontal is x = 45 degrees. Hope my answer would be a great help for you.    If you have more questions feel free to ask here at .

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
