In the figure below, Line segment Eh B is parallel to line segment CD.. In degrees, what is the measure of Angle 4. if the measure of Angle 1 = 50 degrees. and the measure of Angle 3 = 30 degrees.?

Angle C =Angle B = 40° (INTERNAL ALTERNATES)

Angle D =Angle A = 75° (INTERNAL ALTERNATES)

Step-by-step explanation: i got it right on a test

how am i supposed to answer

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
