Question

Find the measureOf an act intercept by and inscribed whose measure is 75°Hent, draw a picture and label it,

Answer 1

From the arc-angle relationships, we know that the inscribed angle is half of the intercepted arc, that is,

`75=(arcAB)/(2)`

Then, by moving the denominator to the left hand side, we get

`\begin{gathered} 2*75=arcAB \\ \text{arcAB}=150 \end{gathered}`

then, the arcAB measure 150 degrees.
