Question

what is ( mwidehat{hi} )?
( mwidehat{hi}=square^{circ} )

Explanation:

Step1: Recall the total degrees in a circle

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

Step2: Set up the equation

Let \(m\widehat{HI}=x\). Then \(x + 100^{\circ}+150^{\circ}=360^{\circ}\).

Step3: Solve for \(x\)

\(x=360^{\circ}-(100^{\circ} + 150^{\circ})\)
\(x=360^{\circ}-250^{\circ}\)
\(x = 110^{\circ}\)

Answer:

\(110\)
