Answer:
Question 10.
angle 1 = 137°
angle 2 = 43°
angle 3 = 137°
reasoning - vertically opposite angles are equal, and angles on a point total to 360 degrees
Question 11.
a) Vertical: I dont know sorry :(
b) Complementary: ∠c and ∠b
c) Suplementary: ∠c and ∠d
d) All adjacent: I dont know sorry :(
e) Find values of all angles, if angle c is 30°: ∠a = 90°, ∠b = 60°, ∠c = 30°, ∠d = 150°, ∠e = 30°
hope this helps :)
