Answer:
base angles: 30°, apex angle: 120°
Step-by-step explanation:
The sine of each base angle is 4/8 = 1/2. The angle whose sine is 1/2 is 30°, so each base angle is 30°.
The remaining angle is 180°-2·30° = 120°.
1,000,000/70=approx 142857 mins
142857/60=approx 2381 hours
2381/24=approx 99 days
If you want the answer more precisely then do the same calculations but use the exact value each time
1. 12 per game
2. 1 game costs 20$
2.25+5.50, 2.50+5.25, 3.49+4.26, etc.
One way is to divide 500 by 0.15
500/0.15=3333.3333333
the answer is about 3333 times
