Answer 2

Step-by-step explanation:

(a.) a+54=90 (angles of rectangles are 90)

a=90-54

a=36

a=b=36 (alternate interior angles)

b=36

(b.)let angle DCE be x

and let angle DEA be y

x+39=90 (angles of rectangle are 90)

x=90-39

x=51

x+78+d=180 (angle sum property of triangle)

51+78+d=180

d+129=180

d=180-129

d=51

d=y=51 (alternate interior angles)

y=51

y+78+c=180 (straight line)

51+78+c=180

c+129=180

c=51
