ao ywah get some hwlp from a pro
Set up an equation 20=k(0.4)....to find k divide 20 by 0.4
|-8| - (5 + 2)2
8-(7)2
8-14= -6
Follow order of operations
Answer:
inverse variation
Step-by-step explanation:
F is inversly proportional to r
1. By the Law of Sines, you have:
SinA/a=SinB/b=SinC/c
2. You don't need the fraction SinC/c, so you can eliminate it. Then:
SinA/a=SinB/b
A=40°
a=19
B=m∠b
b=13
3. When you substitute this values into SinA/a=SinB/b, you obtain:
SinA/a=SinB/b
Sin(40°)/19=SinB/13
SinB=13xSin(40°)/19
m∠b=SinB^-1(13xSin(40°)/19)
m∠b=26.1°
Therefore, the answer is: 26.1 degrees.
