Segment cd is the altitude of right triangle abc. all three triangles in the figure, abc, cbd, and acd, are similar to each other. if p² = xy, then p is the geometric mean of x and y. in this problem, you will work backwards to outline a proof why the height h of altitude cd is the geometric mean of x and y.2a. set up a proportion that will cross-multiply into the equation h² = xy. (2 points)

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
