Answer:

AC = 30 units

Step-by-step explanation:

if AB = BC, then this is an isosceles triangle.

further BX intersects the base (AC) of the isosceles triangle at a right angle.

This means that the line of symmetry BX divides triangle ABC into two congruent triangles where AX = CX.

hence AC is

AX + CX

= CX + CX

= 15 + 15

= 30 units

ollegr [7]

The function which can represent the height, y according to the horizontal distance, x is; Choice A; y = –3/4x + 36.

Which function can represent the height, y, according to the horizontal distance x, from the top of the stairs?

According to the task content; The railing will begin at a height of 36 inches and follow the slant of the stairs. On this note, it follows that the y-intercept of the function is 36.

Additionally, since the railings decreases 9 inches for every 12 horizontal inches, it follows that the slope, m = -9/12 = -3/4.

On this note, the required function is; A.y = –3/4x + 36
