Vertical angles are congruent
2x+50=7x
50=5x
x=10
2(10)+50
20+50
Angle AEB = 70
The reflected figure will appear in quadrant 3, C.
Answer:
57.78 km/hr
Step-by-step explanation:
Total time taken, t = 6 hours
Total distance covered, d = 520 km
Distance by car = 260
Distance by train = 520 - 260 = 260 km
Train speed = x
Car speed = 2x
Average speed speed = 3x /2
Speed = distance / time
1.5x = 520 / 6
9x = 520
x = 520 / 9
x = 57.777
Average speed of train = 57.78 km/hr
Answer:
(a+c)+7
Step-by-step explanation:
this is called the Associative Property
(x+y)+z=x+(y+z)
