Answer:
x = 6
Step-by-step explanation:
Using this theorem to get the other angles of the triangle.
Angle at the vertex is equal to half of the angle at the intercepted arc
For the arc with angle 170degrees
Angle at the vertex = 1/2 * 170
Angle at the vertex = 85 degrees
For the arc with angle 90degrees
Angle at the vertex = 1/2 * 90
Angle at the vertex = 45 degrees
Taking the sum of the 3 angles and equating to 180
85 + 45 + 12x - 22 = 180
130-22+12x = 180
12x = 180 - 108
12x = 72
x = 72/12
x = 6
Hence the value of x is 6
≈120in
The equation for circumstance is 2πr and one tire is 62.83 so two tiers would be 125.66 or ≈ 120
One of the triangle inequalities state that the sum of any 2 sides must be larger than the third side. More importantly, the sum of the smaller two side must be longer than the largest side. So your smaller 2 sides are 1.5 and 2......which has a sum of 3.5. Your third side is 4. So the sum of the 2 sides is NOT greater than the third side.....so these cannot be the sides of a triangle. Hope this helped.
