What do you know to be true about the values of a and b

D . Cannot determined

Step-by-step explanation:

In the given picture , we have two triangles .

In first triangle  , we have three angles given as : 60° , a° and x °.

Here , measure of two angles is not given.

In second triangle , , we have three angles given as : 40° , b° and y °.

Here , measure of two angles is not given.

Also, the information that can link these two triangle is not given.

So , we cannot say anything about the measure of angles a and b.

Hence, he correct answer would be : D . Cannot determined

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
