Answer:
140 + 184 + 165 + 326 = 815/4 = 203.8
86 + 36 + 45 + 126 = 293/4 = 73.3
14 + 36 + 9 + 84 = 143/4 = 35.8
9 + 6 + 7 + 4 + 3 + 6 = 35/6 = 5.8
25 + 42 + 59 + 62 + 18 = 206/5 = 41.2

Answer:
arc AD = 126°
Step-by-step explanation:
the inscribed angles ABD and ACD are half the measure of their intercepted arc AD
then ∠ ABD and ∠ ACD are congruent , so
11x - 3 = 8x + 15 ( subtract 8x from both sides )
3x - 3 = 15 ( add 3 to both sides )
3x = 18 ( divide both sides by 3 )
x = 6
then
∠ ABD = 11x - 3 = 11(6) - 3 = 66 - 3 = 63° , thus
arc AD = 2 × 63° = 126°
Answer:
x = 12
Step-by-step explanation:
Given
2(x - 3) = 9 + 3(x - 9) ← distribute parenthesis on both sides
2x - 6 = 9 + 3x - 27, that is
2x - 6 = 3x - 18 ( subtract 3x from both sides )
- x - 6 = - 18 ( add 6 to both sides )
- x = - 12 ( multiply both sides by - 1 ), thus
x = 12
