1 and 2, because 1+2 is 3, which is less than 6, 2+3 is 5 which is also less than 6.
For triangles, all angles total 180°
For quadrilaterals, all angles total 360°
Parallelograms have equal opposite angles, so each adjacent pair is 180°
Hexagons are 720°
3. 180 - (90 + 30) = 180 - 120 = 60°
4. 180 - (45 + 45) = 180 - 90 = 90°
5. 360 - (135 + 70 + 93) = 360 - 298 = 62°
6. 180 - 60 = 120°
7. 180 - (120 + 37) = 180 - 157 = 23°
8. Perfect hexagon: 120°
9. Parallelogram: 70°
10. 360 - (90 + 90 + 67) = 360 - 247 = 113°
Turing the percentage to a decimal, you get 0.30=0.3
Now making a small equation:
0.3x=24
x=24/0.3
x=80

The distance from the bottom of the wheel to a point on the ground can be modeled by a sine function. h(t)=a*sin(kt)+b. b is the height of the wheel, or 4m. a is the radius of the wheel, 50/2=25m. 2pi/k is the 5sinof thw revolution, so 2pi/k=6/3=2, k=pi. h(t)=25sin(pi*t)+4.
