Answer:
15°
Step-by-step explanation:
sum of exterior angles=360°
each angle=360/24=15°
b
20 ×n=360
n=360/20=18
18 sides
c.
(n-2)×180=174n
180n-174n=360
6 n=360
n=360/6=60
number of sides =60
Answer:
B.) 18
Step-by-step explanation:
90 + 72 = 162
180 - 162 = 18
(90 comes from the right angle)
(72 is already present)
(a triangle adds up to 180 degrees)

There are 3 × 4 = 12 pieces total
14 × 1/4 = 3.5 pizzas needed
not enough, you need two more slices
3π/4 angle is in the second quadrant, so cos (3π/4) is going to be negative.
Reference angle of 3π/4 is (π - 3π/4) = π/4
cos(π/4) = √2/2
cos (3π/4) = - √2/2
Answer is C.
