Answer:
BC ≈ 11.9 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin58° =
=
=
( multiply both sides by 14 )
14 × sin58° = BC , then
BC ≈ 11.9 cm ( to 1 dec. place )
Answer: B=(-3,-5)
Step-by-step explanation:
I am not sure but its might be .125
4(u+3)+3u=-2
distribute: 4u+12+3u=-2
simplify: 7u+12=-2
isolate the variable: 7u=-14
divide: u=-2
check answer: 4(-2+3)+3(-2)=-2
-8+12-6=-2
-2=-2
therefore, u= -2
