what is $mangle qtr$?
$mangle qtr=square^{circ}$

Question

Accepted Answer

# Explanation:
## Step1: Recall the total degrees in a circle
A full - circle has $360^{\circ}$.
## Step2: Set up the equation
Let $m\angle QTR=x$. We know that $x + 150^{\circ}+150^{\circ}=360^{\circ}$ (sum of angles at a point in a circle).
## Step3: Solve for $x$
$$
\begin{align*}
x&=360^{\circ}-(150^{\circ}+150^{\circ})\
x&=360^{\circ}-300^{\circ}\
x& = 60^{\circ}
\end{align*}
$$

# Answer:
$60$
