Answer:
64 ×
Step-by-step explanation:
(8 × 10³)² = (8 × 10³)(8 × 10³)
= 8 × 10³ × 8 × 10³
= 64 ×
The train running at 45 km/hr would pass the jogger running at 9 km/hr after 36 s.
The relative speed of the train to the jogger must be determined to solve for the time that it would take to pass the jogger. The jogger and the train go in the same direction. Therefore, their relative speed would be based on the difference of their speed.
Relative speed = 45 km/hr - 9 km/hr
Relative speed = 36 km/hr
Converting relative speed of km/hr to m/s:
(36 km/hr)(1000 m/km)(1 hr/3600s)= 10 m/s
The formula that will be used is distance/speed.
time= total distance/ relative speed
time = (240 m + 120 m) / 10 m/s
time = 36 s

As stated:
x , the first
2x, the second
3x, the third (sum of first two)
x + 2x + 3x = 180°
6x = 180°
x = 30°
Measures of the Angles would be 30°, 60°, 90°
