9p = 81 degrees

Step-by-step explanation:

All the angles in a triangle equal 180 degrees in total.

So the equation would be:

9p + 7p + 4p = 180

20p = 180

p = 9

So just plug it in:

9(9)                            7(9)                        4(9)

81 degrees            63 degrees            36 degrees

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 .
