Answer:
The distance each car travels per hour is 60t and 45t respectively.
Step-by-step explanation:
Per the pythagorean theorem, The distance function is
sqrt ( (60t)^2 + (45t)^2 ) =
sqrt( 3600t^2 + 2025t^2 ) =
sqrt( 5625*t^2) =
75t
420 = 75t
420/75 = 5.6 hours
5 hours and 36 minutes
Let A=(4,4), B=(8,4) C=(4,8) if P,Q,R are the midpoints of sides AB,BC & CA respectively & ([tex](\alpha ,\beta )[/tex]) be the coordinates of orthocenter of ΔPQR, then the value of ([tex]\alpha +\beta[/tex] ) is
A) 8
B) 6
C) 12
D) 16
3
circumference of Δ ABC
⇒ orthocenter of ΔPQR
