A 15 foot ladder side of the building if the base of the ladder is 6 feet from the bottom of the wall which expression can be used to find the angle formed by the latter and the ground.

The angle formed by ladder and the ground is .

Step-by-step explanation:

Given that, a 15 foot ladder lent against to the side of the building. 6 feet is the distance from the bottom of the ladder to the wall.

It looks like a right angled triangle whose hypotenuse 15 foot and base 6 feet.

We know that,

The angle formed by ladder and the ground is .

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.
