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

Question

Accepted Answer

# Explanation:
## Step1: Recall the total degrees in a circle
The sum of angles around a point (in a circle) is $360^{\circ}$.
## Step2: Set up the equation
Let $m\angle HJI = x$. Then $x+105^{\circ}+ 120^{\circ}=360^{\circ}$.
## Step3: Solve for $x$
$$
\begin{align*}
x&=360^{\circ}-(105^{\circ}+120^{\circ})\
x&=360^{\circ}-225^{\circ}\
x& = 135^{\circ}
\end{align*}
$$

# Answer:
$135$
