Answer:
33.53
Step-by-step explanation:
OB is a radius of the circle, and OC is also a radius of the circle, so both are equal length. That makes ΔOBC an isosceles triangle.
If we cut ΔOBC in half, the angle formed is 125° / 2 = 62.5°.
Therefore:
sin 62.5 = (x/2) / 18.9
x = 37.8 sin 62.5
x ≈ 33.53
Step-by-step explanation:
it will take them 104 hours.
I would believe that it would be correct but I am not 100% on that.
Sorry I couldn't help more:)
Answer: Greater than 3 but less than 17
Step-by-step explanation: To find the smallest possible side, subtract the largest of the given sides by the smallest. To find the largest possibly side, you add both given sides. In this case, you would subtract 7 from 10 to find the smallest side, which would be 3, and add both sides to find the largest possible side of 17.
