<span>The problem is to calculate the angles of the triangle. However, it is not clear which angle you have to calculate, so we are going to calculate all of them
</span>
we know that
Applying the law of cosines
c²=a²+b²-2*a*b*cos C------> cos C=[a²+b²-c²]/[2*a*b]
a=12.5
b=15
c=11
so
 cos C=[a²+b²-c²]/[2*a*b]--->  cos C=[12.5²+15²-11²]/[2*12.5*15]
cos C=0.694------------> C=arc cos (0.694)-----> C=46.05°-----> C=46.1°

applying the law of sines calculate angle B
15 sin B=11/sin 46.1-----> 15*sin 46.1=11*sin B----> sin B=15*sin 46.1/11
 sin B=15*sin 46.1/11-----> sin B=0.9826----> B=arc sin (0.9826)
B=79.3°

calculate angle A
A+B+C=180------> A=180-B-C-----> A=180-79.3-46.1----> A=54.6°

the angles of the triangle are
A=54.6°
B=79.3°
C=46.1°

How many digits are written when 1000 to the power of 2015 is expressed as a numeral?
PtichkaEL [24]

Answer: There are 6046 digits will be written on expansion upto 2015th power.

Step-by-step explanation:

Since we have given that

1000^{2015}

We have to find the number of digits ,

So,

1000^{2015}\\\\=(10^3)^{2015}\\\\=10^{6045}

Since we know that

10^n\text{ has n+1 number of digits }

so,

10^{6045}\text{ has 6046 number of digits }

Hence, there are 6046 digits will be written on expansion upto 2015th power.

You play video games online. When you sign up with the game site, you get 400 points. You earn 50 more points for each hour that
aleksley [76]
The answer is 12 but the way you get it is you subtract 400 from 1000 which gives you 600 then you divide 600 by 50 to get 12. So it looks like this 1000-400= 600, 600/50=12. Hope this helps. :)

If all of the people that live in your home bought one 360 pound hamburger from Mallie’s Sports Grill and ate 2/3 pound servings
Vsevolod [243]
We have 4 people in our home
so total bought 360 pounds of hamburger
each ate 2/3 pound every day
so 360-(amount eaten per day) times (number of days)=0 (0 because we want it to be gone)
number of days=x unknown
amount eaten per day=(number of people) times (amount eaten per person per day)
amount eaten per day=4 times 2/3 lb=8/3
360-8/3 times x=0
360-8/3x=0
add 8/3x to both sides
360=8/3x
multiply both sides by 3/8
1080/8=x
135=x
it would take 135 days or about 4 months or 1/3 year, assuming that my family doesn't get tired of it and that my reletives don't visit and take a whole bunch to bring home.

4 people takes 135 days
