The upper left and bottom right are functions.
Remember a function has to pass the vertical line test. Elements from the domain cannot repeat, but elements from the range can.
Answer:
m∠2= 180-30=150
m∠3= 30
m∠4=30
m∠5=150
m∠6=150
m∠7=30
Step-by-step explanation:
since these are angles of parallel lines cut by a transversal the theorems of vertical, corresponding, supplementary, and complementary angles apply.

Step-by-step explanation:
the circumference of a circle is
2×pi×r
with r being the radius, which is always half of the diameter.
r = 1.8 / 2 = 0.9 cm
circumference :
2×pi×0.9 = 1.8×pi = 1.8 × 3.142 = 5.6556 cm ≈ 5.7 cm
