the decimal expansion is 0.31818181818182
Answer:
112°
Step-by-step explanation:
Arc CD is part of arc BCD, which is intercepted by the inscribed angle A.
Based on the inscribed angle theorem on circle, the sum of arc CD and CB is twice the measure of angle A.
That is:
CD + CB = 2(129°)
CD + 146 = 2*129
CD + 146 = 258
Subtract 146 from both sides to find CD
CD + 146 - 146 = 258 - 146
CD = 112°
It would be 1,300. When rounding, you'd need to look at the number to the right of the place you're rounding to. In this case, you're rounding to the hundreds place (the 2), so you look at the number to the right (7). To know if you round up or down use this:
Round down= 0-4
Round up= 5-9
