Answer:
30°
Step-by-step explanation:
Angle C = 55°, Angle D = Angle A = 65°, Angle B = 2x
Sum of angles in a triangle = 180°
65° + 55° + 2x = 180
120 + 2x = 180
2x = 180 - 120
2x = 60
x = 30°
d) neither parallel or perpendicular
A - 24!
-21 as its true value is 21
-3 as its true value is 3
if you add them together you get 24!
Hope this helped ^^
