<h2>○=> <u>Correct option</u> :</h2>

\color{plum} \bold{ \tt \:  \bold{C.  \$20,652.00}}

<h3>○=> <u>Steps to derive correct option</u> :</h3>

Selling price of a car = $19,000

Percentage of sales tax in the city = 8.3%

Sales tax :

= \tt  \frac{8.3}{10 \times 100}  \times 1900

= \tt  \frac{8.3 \times 19000}{1000}

= \tt  \frac{1577000}{1000}

\color{plum} = \tt  \$1577

Thus, the sales tax on the car = $1577

Cost of license and title = $75

Total price of car :

= Cost price of car + Sales tax + cost of license/title

=  \tt19000 + 1577 + 75

\color{plum} = \tt  \$20652

Thus, the total purchase price of the car = $20,652.00

Therefore, the correct option is <em>(C) $20,652.00</em>

Can someone help me. Please
Lerok [7]

Step-by-step explanation:

a. the angle B in triangle ABC:

180-47=133°

angle C in ABC:

180-(40+133)=7°

using sine rule:

a/sin A= b/sin B= c/sin C

50/sin 7= BC/sin 40

BC= (50*sin40)/ sin7

=263.7 m

b.sin 47= opposite/hypotenuse

sin 47= CD/263.7

CD= sin 47*263.7

= 192.9
