What is the measure of the arc from A to B that does not pass through C?
sergeinik [125]

Applying the inscribed angle theorem, the measure of the arc from A to B is: 100 degrees.

<h3>What is the Inscribed Angle Theorem?</h3>

The inscribed angle theorem states that an inscribed angle in a circle is half the central angle.

Angle BAC = 40 degrees, so, central angle = 80 degrees. Arc BC would also be 80 degrees.

Measure of arc AC through point B = 180 degrees.

Arc AB = 180 - 80 = 100 degrees.

Natalka [10]

Hello!

ANSWER

The painting would cost $387.45.

____________________________________________________________

EXPLANATION

2' 3" = 27"

3' 5" = 41"

Multiply the length by the width (in inches) of the painting.

27 * 41 = 1107

We now know that the area of the painting is 1107in.^{2} Next, multiply the cost per square inch (0.35) by the total amount of square inches (1107).

.35 * 1107 = 387.45

Mystery number: The number is less than 190000 and greater than 180000.
Kipish [7]
The answer to it is    
180, 000 <n> 190, 000 
180,000 + 2000 = n = 5000-187, 000 
182,000 = n = 182, 000   
Or,  
 180, 000 <n> 190,000                     
 n + 5000= 187, 000                           n – 2000 = 180, 000 
 n= 187, 000- 5000                             n = 180, 000 + 2000 
 n= 182, 000                                       n= 182, 000
