Question

what is ( mangle gjh )? ( mangle gjh=square^{circ} )

Explanation:

Step1: Recall the total degrees in a circle

A full - circle has \(360^{\circ}\).

Step2: Set up the equation

Let \(m\angle GJH=x\). Then \(x + 145^{\circ}+125^{\circ}=360^{\circ}\) (since the sum of angles around a point \(J\) in the circle is \(360^{\circ}\)).

Step3: Solve for \(x\)
