Step-by-step explanation:
Since the triangles are right use trigonometric ratios to find x and y
A
sin33° = =
Multiply both sides by x
x × sin33° = 2.5 ( divide both sides by sin33° )
x = ≈ 4.590
tan33° = =
Multiply both sides by y
y × tan33° = 2.5 ( divide both sides by tan33° )
y = ≈ 3.850
B
cos72° = =
Multiply both sides by x
x × cos72° = 6 ( divide both sides by cos72° )
x = ≈ 19.416
tan72° =
Multiply both sides by 6
6 × tan72° = y, thus
y ≈ 18.466
Step-by-step explanation:
small circle
C= pi D
C = 3.1415(9)
C= 28.3 ft
large circle
C= 2(3.1415)(7)
C = 44 ft
Add 28.3 + 44 = 72.3 ft

N= night c= child
sandy= $10+$5c
kimmi= $25n
if sandy babysits 3 children for one night they will both be the same price
sandy= $10+5(3)=$25
kimmi= $25
