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,

$\begin{gathered} 7x+1+9x-7=180^{\circ} \\ 16x-6=180^{\circ} \\ 16x=180+6 \\ x=\frac{186}{16} \end{gathered}$

So,

$undefined$
