Answer:
a=41.8 BC=2.8
Step-by-step explanation:
sin30/6=sinx/8
8*sin30=6sinx
4=6sinx
sin^-1(4/6)
angle a
cosine rule
bc^2=3^2 +5^2-2(3)(5)*cos30
BC^2=
BC=2.83
2.8
Answer:
40.625%
Step-by-step explanation:
This is a very simple question.
We have to understand converting word equations to algebraic ones.
"is" means "="
"of" means "*"
So, we can write:
39 = what percent * 96
Now, we let "what percent" be "p" and solve the equation for p:
39 = P * 96
So,

Converting this decimal to percentage means multiplying by 100, so we have:
0.40625 * 100
= 40.625%
1/100+1/100+1/100 Hope this helped! I remember taking this unit in Elementary. Good luck!
