For this case, using the law of cosine we have:
c ^ 2 = a ^ 2 + b ^ 2 - 2 * a * b * cos (C)
Substituting values we have:
c ^ 2 = 10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105)
Clearing c we have:
c = root (10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105))
c = 14.33216827
round the answer to the nearest tenth:
c = 14.3
Answer:
the length of side c is:
c = 14.3
Answer:
500
Step-by-step explanation:
3000 divided by 6
Hope this helped, sorry if I'm wrong!
1. Factor x^2+9x+20
((x+4)(x+5))/(x+3)*(x^2-x-12)/(x^2+3x-4)
2. Factor x^2-x-12
((x+4)(x+5))(x+3)*((x-4)(x+3)/(x^2+3x-4)
3. Factor x^2+3x-4
((x+4)(x+5))/(x+3)*((x-4)(x+3))/((x-1)(x+4))
4. Simplify
((x+4)(x+5)(x-4)(x+3))/((x+3)(x-1)(x+4))
5. Cancel x+3
((x+5)(x-4))/(x-1)
Have a nice day
