Question

PLEASE HELP, help me find the arc measurement, show work pleasep

Answer 1

Since arcGJ represents half circle, then

$arcGJ=180$

We can also note that

$arcGJ=arcGH+arcHJ$

since arcGH measures 55 degrees, by substituting this value and our first result into this equation we get

$180=55+arcHJ$

which gives

$\begin{gathered} arcHJ=180-55 \\ arcHJ=125 \end{gathered}$

Therefore, arc HJ measures 125 degrees
