Question

What is the arc measure, in degrees, of ADC on circle P below?

Answer 1

Answer: THE EXERCISE IS INCOMPLETE. BELOW IS THE EXPLANATION OF A SIMILAR EXERCISE.

Explanation:

The question is incomplete because you did not provide the figure, so I will show you how to solve a similar exercise.

See the picture attached. You can observe that:

`ADC=(4y+6)\°+(7y-7)\°`

By definition, there are 360 degrees in a circle. Based on this, you can write the following equation:

`(4y+6)+(7y-7)+(20y-11)=360`

Then, you need to solve for the variable "y" in order to find its value. You get that this is:

`4y+6+7y-7+20y-11=360\\\\31y-12=360\\\\y=(360+12)/(31)\\\\y=12`

Knowing the value of "y", you can substitute it into the first equation and evaluate. Then, you get the following result:

`ADC=(4(12)+6)\°+(7(12)-7)\°\\\\ADC=131\°`
