Sinα=h/w
w=h/sinα, we are told that h=15 ft and α=70° so
w=15/sin70° ft
w≈15.96 ft (to nearest hundredth of a foot)
For question number 1, the correct answer would be the x coordinate would be the same, or will not change.
For question number 2, the correct answer would be (-4,-7)
For question number 3, the correct answer would be <span>A'(5, -3), B'(2, -1), C'(-2, -4)
For question number 4, the correct answer would be </span><span>R'(-3, 2), S'(-5, -2), T'(-6, 0)

Answer:
1st angle = 30
2nd angle = 60
3rd angle = 90
Step-by-step explanation:
- let ,1st angle be x , 2nd angle be 2x and 3rd angle be 3x
- x+2x +3x =180
- 6X =180
- x =180/6
- x =30
Answer:
The equation of the circular wheel is
.
Step-by-step explanation:
Given :
Radius of Ferris wheel r = 70 feet.
The distance between the wheel and the ground = 4 feet.
Also, the rectangular coordinate system shown has its origin on the ground directly below the center of the wheel.
So the x coordinate of center of wheel must be 0 , and y coordinate = 70 + 4 = 74
Thus, Coordinates of center = (0,74)
The equation of circle is given by :-

Now center (h,k) = (0,74) and r = 70 , we get

Hence, the equation of the circular wheel is
.
