Answer:option C is the correct answer.
Step-by-step explanation:
When the ladder leans against the wall, it forms a right angle triangle with the wall. The length of the ladder becomes the hypotenuse of the right angle triangle.
Since the length of the ladder is 12 foot, then
Hypotenuse = 12 foot
The angle formed by the ladder with the ground is 75.5 degrees. Therefore, the height, y which is the distance from the point where the ladder touches the wall to the foot of the wall becomes the opposite side. It would be determined by applying trigonometric ratio
Sin θ = opposite side/hypotenuse
Sin 75.5 = y/12
From the information obtained from the question, two equations can be created:
Let x and z be the two numbers (parts)

. . . . (1)

. . . . (2)
By transposing (2), make 'z' the subject of the equation

. . . . (3)
By substituting (3) into equation (1) to find a value for x




⇒

∴ either

OR

Thus x = 5 or x = 10
By substituting the values of x into (2) to find z
z + (5) = 15 OR z + (10) = 15
⇒ z = 10 OR z = 5
So, the two numbers or two parts into which fifteen is divided to yield the desired results are 5 and 10.
Answer:
<h3>Step 1 - Find the gradient of 2x + 4y = 16</h3>
2x + 4y = 16
4y = 16 - 2x
y = 4 - 1/2x
gradient = -1/2
<h3>Step 2 - Find the Equation</h3>
y - y1 = m(x - x1)
m = gradient, (x1, y1) = (-2,2)
y - 2 = -1/2 (x + 2)
y - 2 = -1/2x - 1
y = -1/2x + 1 → ANSWER
