Answer:
Step-by-step explanation:
Angle BOA = length of arc/radius
=8.4/8
= 1.05 radians
= 1.05*180/pi
= 60.16°
= 60°
Angle AOC = 45°
Angle BAC = 60.16 + 45
= 105.16°
Arc BAC = radius * angle (degrees) * pi /180
= 8 × 105.16 × (3.14159/180)
= 14.683 cm
= 14.7 cm

Answer:
24;120;201600
Step-by-step explanation:
25. 3 salads, 4 main courses, 2 vegetables, 1 dessert
3*4*2*1=24
26. 5*4*3*2*1=120
27. 8*7*6*5*5*4*3*2*1= 201600
Answer:
Cos(θ) = 8 / 17
Step-by-step explanation:
<em>Cos = Adjacent / Hypotenuse</em>
Side that is adjacent to θ = 8
hypotenuse of the triangle = 17
<u>Cos(θ) = 8 / 17</u>
