Radius =
9^2 + 9^2 = d^2
d = sqrt(162), about 12.73
theta =
atan(9/-9)
is 45°, but in 2nd quad, so add 90
(12.727, 135°)
Answer:
76
Step-by-step explanation:
decagon = 10 sides
3 heptagons = 3 × 7 = 21 sides
3 nonagons = 3 * 9 = 27 sides
3 hexagons = 3 * 6 = 18 sides
10 + 21 + 27 + 18 = 76 sides in total
