Question

What is the arc measure of minor arc AD in degrees?PАB(7x + 1)(9x – 7)DС

Answer 1

As per given by the question,

There are given that a circle for finding the arc AD.

Now,

`\angle APD=(7x+1)^(\circ)`

And,

`\angle CPB=(9x-7)^(\circ)`

Then,

The total sum of the semicircle is 180 degree.

So,

`(7x+1)+(9x-7)=180^(\circ)`

Then,

`\begin{gathered} 7x+1+9x-7=180^(\circ) \\ 16x-6=180^(\circ) \\ 16x=180+6 \\ x=(186)/(16) \end{gathered}`

So,
