The base of an isosceles triangle is seven less than twice one of the congruent sides. If the perimeter of the triangle is 63 cm, find the length of each side.

17.5

Step-by-step explanation:

let 'x' = each congruent side

let '2x - 7' = side of base

x + 2x - 7 = 63

3x = 70

x = 17.5

5x+10 is the correct one

hope this

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 .
