Answer:
D) 5
Step-by-step explanation:
Using cosine law
b² = 10² + 12² - 2(10)(12)cos(24)
b² = 24.74909017
b = 4.974845743

Wow you needed help and nobody help, thats mean.
Answer:
It's 5.
Step-by-step explanation:
Because a constant is a number next to the variable.
Notice that the 2 expressions have 2 common terms.
(r-s) is just (s-r) times (-1)
similarly
(t-s) is just (s-t) times (-1)
this means that :
(r-s) (t-s) + (s-r) (s-t)=-(s-r)[-(s-t)]+(s-r) (s-t)
the 2 minuses in the first multiplication cancel each other so we have:
-(s-r)[-(s-t)]+(s-r) (s-t)=(s-r) (s-t)+(s-r) (s-t)=2(s-r) (s-t)
