Mathematics

Answer: The correct answer is option B: The vertical angle

Step-by-step explanation: Please refer to the picture attached for further details.

The circle with center O has an arc AB with a central angle of 42 degrees as shown in the diagram (not draw to scale).

If the line A is extended to point D and also line B is extended to point C both along the circumference of the circle O, then you would have another arc CD on the circle.

If two intersecting lines AD and BC form a pair of angles (shown here as 42° and x°) the angles are called vertical angles, and vertical angles in a circle are equal.

Hence the only thing that can be shown to measure 42 degrees in the question above is a vertical angle.

A store owner paid $15 dollars for a book. she marked up the price of the book by 40% to determine it's selling price.
Tcecarenko [31]
A) $15 ÷ 40% =
15×.4= 6
15+6= 21

B) $38 × .25=9.5
38-9.5=28.50

28.50×.06=1.71
28.50+1.17=30.21

I think this is how you do it. would wait for other answers as well to double check.
