∠aed is formed inside a circle by two intersecting chords. if minor arc bd = 82 and minor arc ca = 176, what is the measure of ∠ aed?

 .5 * 258 = 129 degrees because these are interior angles. 258 is given from the fact that you add 176 and 82. Then you do 360 -258, which equals 102 degrees, and then, because they are vertical angles, your angles are equal so angle AED = 51 degrees

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
