does anybody know it

|dw:1434665580771:dw| this is the diagram, using the normal notation for the triangle

4. MrNood

OK so you can use the cosine rule to find an angle here Do you know the cosine rule equation?

5. anonymous

i just need the answer from one of these four degrees 22, 38, 142, 158,

6. MrNood

You just need to understand how to get the answer using the cosine rule. If oyu are not willing to do that please say so now...

7. anonymous

i dont know it

8. MrNood

But that is evidently what you are currently studying. Have you been taught any other way to solve this question?

9. anonymous

no im just using this sight to get the answers

does anybody know the degree to this If the sides of a triangle are 3, 4, and 5, then, to the nearest degree, the measure of the smallest angle of the triangle is

11. MrNood

This site (not sight) is not for getting answers - it is against the rules. You will not learn anything by taking answers from people oyu don't know - MANY of the people who claim to help here actually know no more than you. The best way to th eanswer is to apply and understand the equation

who cares bro i work way harder then you ever will im a 2 time state champ wrestler at sunnyside high ranked number 1 in the country

13. MrNood

the cosine formula is $b ^{2} =a ^{2}+c ^{2} - 2 ac \cos (B)$ solve that for B

14. anonymous

i dont want to im just looking for the answer

15. anonymous

if you know it then give me it i would apricate it but if not then leave me alone

16. MrNood

Congratulations on your sporting success. I truly hope (but strongly doubt) that it is sufficient to earn you a living (throughout your whole life when you are too old to 'wrestle for a living'!) in the absence of any other educational achievement

owe you want to bet you couldnt win one match if your life depended on it

18. MrNood

You are absolutely right. You will probably find you need skills other than the ability to hold a man on the ground for 3s to get through life

19. anonymous

i have way more skills than you do will see who wins in a fight if your man enough

20. MrNood

But winning a wresting fight is a very limited way of judging your worth. How do you intend to support yourself and family as an adult?

21. MrNood

However, I can see that it is not going to require the law of cosines, so good luck.

22. anonymous

if you dont know im one of the best i dont think youve ever heard of freestyle wrestling you could wrestlie for a long time and in the olypimcs whcich is where im going

23. MrNood

Genuinely - Good luck

yeah what ever bro oh and i got the answer
