The measures of two vertical angles are 27° and (2x + 1)º. Find the value of x. The value of x is

x = 13

Step-by-step explanation:

Vertical angles are equal

2x + 1 = 27

Subtract 1 from both the sides,

2x = 27 - 1

2x = 26

Divide by 2 on both the sides,

x = 26/2 = 13

For this case we have by definition, that the area of a circle is given by:

Where:

A: It is the area of the circle

r: It is the radius of the circle

We cleared the radius of the circle:

We choose the positive value:
