M∠abc=138° and m∠def=31° . which statement is true about ∠abc and ∠def ? a)the angles are neither complementary nor supplementary. b)the angles are supplementary. c)the angles are complementary.

The angles are neither complementary nor supplementary.

Step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
