Given:

m∠APD = (7x + 1)°

m∠DPC = 90°

m∠CPB = (9x - 7)°

To find:

The measure of arc ACD.

Solution:

<em>Sum of the adjacent angles in a straight line = 180°</em>

m∠APD + m∠DPC + m∠CPB = 180°

7x° + 1° + 90° + 9x° - 7° = 180°

16x° + 84° = 180°

Subtract 84° from both sides.

16x° + 84° - 84° = 180° - 84°

16x° = 96°

Divide by 16° on both sides.

x = 6

m∠APB = 180°

m∠BPD = (9x - 7)° + 90°

             = (9(6) - 7)° + 90°

             = 47° + 90°

m∠BPD = 137°

m∠APD = m∠APB + m∠BPD

             = 180° + 137°

             = 317°

<em>The measure of the central angle is congruent to the measure of the intercepted arc.</em>

m(ar ACD) = m∠APD

m(ar ACD) = 317°

The arc measure of ACD is 317°.

Answer:

Step-by-step explanation:

each box has 12 melon for 15 dollars:

the price of one melon : 15/12=1.25 dollar each

he bought 12 boxes of melon and paid 15 dollars for each :

12*15=180 dollars

total melon is : 12*12=144 dollars

he sold 3/4 of a melon : 3/4 *144=108

the cost of 108 : 108*1.25= 135 dollars

at a price of $ 1.6 = 108*1.6= 172.8

the rest of the melon sold at reduce price=

144-108= 36

over all profit = 15 %

180*(1+0.15)=207 dollars profit

selling 108 melons : $172.8

overall profit - profit from selling 108 melons: 207-172.8=$34.2

<h2>reduced price = 34.2/36=0.95 dollars</h2>
