Answer:
Well the original price would be $44
Step-by-step explanation:
So make an equation
Lets make X stand for the price before the deduction
so x-x(0.3)=30.80
Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change
Now just solve the equation
You’ll get 44.

Answer:
b = 7.76
Step-by-step explanation:
ABC is a triangle. In a triangle, we have the formula as following:
+) Cosine ∠An angle = 
As we can see in the figure, Angle B has:
+) Adjacent side a is BA = 10
+) Adjacent side b is BC = 12
+) Opposite side is AC = b
The measure of Angle B is 40°.
Replace these into the formula, we have:
+) Cosine ∠B = 
⇔ Cosine 40° = 
⇔ 0.766 = 
⇔ 0.766 x 240 = 244- b^2
⇔ 183.84 = 244 -b^2
⇔ b^2 = 244 - 183.84 = 60.16
⇔ b = 
= 7.76
