Answer:
x = 7, arc DE = 198°
Step-by-step explanation:
Inscribed angles from the same arc are congruent.
∠ DCE and ∠ DWE are inscribed angles from the same arc DE , thus
12x + 15 = 3x + 78 ( subtract 3x from both sides )
9x + 15 = 78 ( subtract 15 from both sides )
9x = 63 ( divide both sides by 9 )
x = 7
Thus
∠ DCE = 12x + 15 = 12(7) + 15 = 84 + 15 = 99°
The inscribed angle DCE is half the measure of its intercepted arc, thus
arc DE = 2 × 99° = 198°

you just divide 2 by 10, which is
.2
Answer:
it expanded is the south
Step-by-step explanation:
Jessica is purchasing a new car whose MSRP is $19,750. She is trading in her old car for $8100.
Without the upgrade package and delivery charge , the cost of her car is
19,750 - 8100 = $11650
upgraded cost = $6000 and Vehicle delivery = $600. we add the upgraded cost and delivery cost.
Total cost of car = 11650 + 6000 + 600 = $18,250
