What is the value of x? Test is timed please help.
Darina [25.2K]

Answer:

x = 19

Step-by-step explanation:

A circle has a total of 360 degrees. Because central angles are congruent to the degree measures of their arcs, and because of vertical angles we can construct the equation :

5x+37+5x+37+3x-9-9=360

We can simplify this to :

8x+28=360

Subtract 28, divide 8, and x is 19
