Angle DAC is an exterior angle (because it son the exterior of the triangle) and idk the choices for the measure of Angle DAC are.... but i know that X is equal to 119 beacse that line its on makes a 180 degree line with 61. so 180-61 is equal to 119
The formula is C=2π<span>r Knowing that you radius is 12, input that in you equation. Also, use 3.14 as </span><span>π So, solve using </span>C=2(3.14)12 This will give u C
