In one year there are 365 days of 24 hours. Each hour has 60 minutes and each minute is 60 seconds long. So, 60s/min x 60 min/hr x 24hr/day x 365 days equals 31,536,000s.

Hope this helps you with your answer. If it is incorrect, then I am sorry.

I'm going to do this in meters which will turn into km. which you can then convert into miles.

The speed of light is 2.998 * 10 ^8 meters /second

2.998*10^8m/s[3600 s/hr]*[24 hrs/day]*[365 days/year]

2.998*10^8 * 3600 * 24 * 365 = 9.45*10^15 m/year

9.45*10^15 m/year / 1000 m/km = 9.45 * 10^12 km/year

If you want miles, just divide this number by 1.6

9.45 * 10^12 / 1.6 = 5.91 * 10^12 miles / year. When you google this, the answer they give is 5.87 * 10^12 miles / yr. The difference is in where you round, the use of an approximate 1.6 and the length of a year.

What is the measure of the other acute angle ?

Vaselesa [24]

Answer:

$62^{o}$

Step-by-step explanation:

All the angles in a triangle add up to $180^{o}$

Every right angle triangle has a right angle in it which is $90^{o}$

So to find the remaining angle, you do $180^{o}$ - $90^{o}$ - $28^{o}$ = $62^{o}$
