y=88

Step-by-step explanation:

Since y is in a triangle, the sum of ALL 3 ANGLES MUST equal 180°, so that means 180-(53+39)=180-92=88°

88

Step-by-step explanation:

all angles inside a triangle have to equal 180 so if you add 53 and 39 you get 92 so u subtract 92 from 180 and that equals 88

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 .
