Question

Use the circle shown to answer the question. If the measure of arc AB is 110° and mZACB - (5x-20), find the value of x. 15 48 26 55

Answer 1

in this case we can made the arc equal to the angle so we have the equation:

`110=5x-20`

and we solve for x so:

`\begin{gathered} 110+20=5x \\ (130)/(5)=x \\ 26=x \end{gathered}`
